## How much resistance does a 60 watt bulb have?

The filament in a 60 watt bulb has a resistance of 240 ohms as compared to 145 ohms for a 100 watt bulb. The above assumes that the voltage source is constant at 120 volts.

## What is the resistance of 120v?

For example, a 100 watt light bulb operating on 120 volts AC will have 144 ohms of resistance and will draw 0.833 Amps.

## What is the current in a 60 watt bulb connected to a 120 volt source?

Question: Problem 3 A 60-W (60 Watts) light bulb connected to a 120-V (120 Volts) source draws a current of Answer: 0.5 A (0.5 Amps).

## How many ohms is 60 watts?

In fact, the 120-Watt bulb would have a current of 1 Amp and a resistance of 120 Ω; the 60-Watt bulb would have a current of 0.5 Amp and a resistance of 240 Ω.

## Which has more resistance 60-watt or 100 watt?

A 60-watt bulb has a higher electrical resistance than a 100-watt bulb. Because power is inversely proportional to resistance, when the power is less, the resistance is high.

## What is the resistance of a 120 volt 100w bulb?

For example, a 100 watt light bulb operating on 120 volts AC will have 144 ohms of resistance and will draw 0.833 Amps.

## How many ohms are in a Volt?

Ohm to Volt/ampere Conversion Table

Ohm Volt/ampere [V/A]
0.01 ohm 0.01 V/A
0.1 ohm 0.1 V/A
1 ohm 1 V/A
2 ohm 2 V/A

## How much current is in a 60 W bulb connected to 120V?

Here power is 60 watts. voltage is 120 so voltage x 0.5 amperes will make the power 60 watts. current= 0.5 amperes.

## How much current flows through a 60 W light bulb that is connected to a 120 V electrical line?

How many amperes flow through a 60-W bulb connected in a 120 V circuit? Ans. Power= current x voltage. Rearranging terms we find that current = power/voltage = 60W/120V = 0.5 Amps.

## What is the current that flows through a 60 W light bulb if it is connected to a 110 V source?

So the calculation is divide the Wattage by 110. For example: A 40 Watts bulb draws 0.36 Amps to operate. A 60 Watts bulb draws 0.54 Amps to operate. A 80 Watts bulb draws 0.72 Amps to operate.
