What is the current passing through a light bulb that is marked with 60 W 120 V if it is connected to a 120 V power supply?

I=60/120=0.5amp.

How much current flows through a 60 watt light bulb that is connected to a 120 volt power 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.

How many amperes does a 100 watt bulb require when operating on 120 volts?

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 rate of energy dissipation for a 120 V 40 W light bulb?

4.44 watts
We have 120 V/(360 + 360 + 360) ohms = 1/9 A. The power dissipated in each bulb is either (1/9)2 × 360 = 4.44 watts, or (1/9) × 40 = 4.44 watts.

What is the resistance of A 60-watt light bulb?

240 Ω
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.

How many amperes flow through A 60-watt bulb?

A 60 Watts bulb draws 0.54 Amps to operate.

How many amperes flow through a 60-watt bulb?

What is the current flow in the bulb formula?

We are given the voltage and the power output of a simple circuit containing a lightbulb, so we can use the equation P=IV to find the current I that flows through the lightbulb. 19.51P=IVI=PV=60 W120 V=0.50 A. Thus, a half ampere flows through the lightbulb when 120 V is applied across it.

How many amps does a 60 watt light bulb use?

A 60 Watts bulb draws 0.54 Amps to operate. A 80 Watts bulb draws 0.72 Amps to operate.

How does a 60w bulb work or show light?

The rating 60 Watts means that the bulb will consume 60 Joules/sec and convert it into heat and light. Power = Voltage x Current. If the power supply is 120 Volt (It is usually 110–120 V in the US), then a current of 60/120 Ampere or 0.5 A will enter (and leave) the light bulb.

How much current does a 60w bulb draw?
