Which has a larger resistance a 60 W lightbulb or a 100 W lightbulb?

Power is exactly proportional to resistance in this case, therefore a high-power-rating bulb with a 100-watt rating will have a higher resistance than one with a lower power rating. In this case, the power is inversely proportional to the resistance, hence the resistance of 60 W will be greater than the resistance of 20 W.

In the same way, which bulb has more resistance: a 100 W bulb or a 60 W bulb?

Using the assumption that the voltages of two bulbs are the same, the resistance of the bulbs is equal to V/100 and V/60 for the corresponding bulbs. As a result, it has been shown that the 60W bulb has more resistance than the 100W bulb.

Also, which bulb will provide a greater light when connected in series: a 60w or a 100w?

P=I2R, where I is the current, and for bulbs linked in series, since the current through both bulbs is the same, the bulb with the bigger resistance (a 60W bulb) would expend more power, and hence be brighter, than the bulb with the lower resistance (a 30W bulb) (100W bulb).

In a similar vein, one can inquire as to what the current is flowing through a 60 W lightbulb that is attached to a 120 V outlet.

Physics 4-26 is a physics course that focuses on the fundamentals of physics.

1.8 volts

What is the current drawn by a 60W bulb when it is connected to a 120V power supply?

0.5 Amps is the maximum amount of current available.

Approximately how much energy is used by a toaster with a resistance of 40 ohms that is hooked into a 120 V power source?

a power of 360 watts

Approximately how much resistance does a 60 watt light bulb have?

A 120-watt bulb, for example, would have a current of 1 Amp and a resistance of 120 Ohms; a 60-watt bulb would have a current of 0.25 Amp and a resistance of 240 Ohms.

Is it true that increased power equals more resistance?

To address your first question, a 100W light bulb has lower resistance because, as long as the light bulb resistance is greater than the wire resistance, you may take use of the equation P=I squared R to reduce the resistance of the light bulb. Simply decreasing the resistance a little amount results in a rise in current.

In what unit of measure is the resistance of a 100 W bulb?

144 ohms is the resistance.

What is the best way to determine the resistance of a light bulb?

Because it includes the relationship between power voltage, current, and resistance, using the formula I=P/V with P and V known to determine the current, and then using the formula R=P/I2 to find the resistance, will be the appropriate steps to follow in order to complete the circuit.

Which of the following is the proper formulation of Ohm's law?

Ohm's law states that the voltage or potential difference between two points is directly proportional to the current or electricity passing through the resistance, and that the resistance of the circuit is inversely proportional to the voltage or potential difference between two points, as shown in the diagram. Ohm's law may be expressed mathematically as V=IR.

Which bulb produces a greater glow: a 40-watt or a 100-watt bulb?

It has been shown again again that when two 80W bulbs are linked in series, the power dissipation is larger than when two 100W bulbs are connected in series. As a result, when two 80W bulbs are linked in series, the 80W light will shine brighter than the 100W bulb.

What happens to the current if the resistance is increased by a factor of two?

When the resistance is doubled, the current decreases by one-fourth, indicating that the current is inversely proportional to resistance. Because resistance is inversely related to the amount of current flowing in a circuit, doubling the resistance would result in a halves of the current. In other words, if the resistance is doubled, the current will be cut in half.

Do light bulbs have a high or a low resistance to electricity?

When there is less current, the resistance must be high, and when there is more current, the resistance must be low. In a series circuit, when the number of bulbs is increased, the overall resistance increases, and the battery's output current decreases accordingly. This current passes through each of the bulbs, making them seem dimmer as a result.

Is a watt of resistance equal to one watt?

It is said that the current equals the voltage divided by the resistance, or I = V/R, and that the voltage equals the resistance. This is analogous to lowering the resistance in an electrical circuit, which results in an increase in the amount of current flowing. Watts are the units of measurement for electrical power.

In this case, it signifies that the light bulb has a rating of 60 watts.

When we talk about a bulb with a 60-watt rating, we are merely referring to the fact that the product of the operating voltage and current is 60. The bulb, on the other hand, is engineered to work with a certain voltage. As a result, the bulb must have a wattage rating as well as a voltage rating for functioning.

What will result in a reduction in the current flowing through an electrical circuit?

According to the law of reciprocity, the current in a circuit is directly proportional to the electric potential difference impressed across it, and it is inversely proportional to its resistance. Increasing the resistance (option B) or decreasing the voltage (choice A) are two methods of lowering the current (choice D).

What arrangement results in the brightest illumination of two bulbs?

When the bulbs are connected in series, each bulb receives the entire voltage V, resulting in P=V2R. Because a bulb shines brighter when it receives more electricity, connecting many bulbs in parallel will result in a brighter light. The parallel arrangement of resistors, as you can see, lowers the effective resistance of the system.

What is the formula for calculating the power of a light bulb?

Every second, a one-watt light bulb uses one joule of electrical energy. Multiply (1 joule/second) by (30 watts) multiplied by (5 minutes) multiplied by (60 seconds/minute). This yields 9000 joules as the total amount of energy utilised in your example.

How do you calculate resistance using Watts?

Example: If the power is 100 watts and the voltage is 50 volts, the current will be 100/50, which is equal to two amps. Calculate the resistance in Ohms by dividing the voltage by the current and multiplying the result by 100. Ohm's law indicates that voltage equals current multiplied by resistance; thus, by rearranging the formula, resistance equals voltage divided by current.

What is the wattage of a light bulb?

For example, consider the power of a 100-watt light bulb. The power rating of the bulb is shown here. It shows us how much power can be converted into light and heat by the bulb in a particular length of time (in this case, one hour). A 25-watt bulb will use 25 Watt-hours (Wh) of electricity if it is kept on for one hour.
