What is the current in an circuit with 120-volts and a 60-watt light bulb?

Use the formula P= VI (power = potential x current) where (watts = volts x amps).
The current I in amperes is equal to the watts divided by the volts, 40/120.
The bulb is using 1/3 amp of current.

∙ 13y agoP=V² / R , P=I² x R. We dont have an equation to relate directly the variables your given, BUT, we CAN solve for R, and plug back into one where we CAN relate them!
R= V² / P. Take that value, go back to your power equations, isolate for I, I= Square root of (P/R)

The equation is power = current x voltage. (Watts = amps x volts) re arranging the equation will give you; Amps = watts/volts. This will give you the answer that you are looking for.

∙ 14y agocurrent.....(A)....u gotta tell me the resistance (Ohms). Then, A (currrent) = V(volts) divided by R(resistance) loll i just had a science test on this today

What is the current in an AC circuit with a 120-volts and a 60 watt light bulb?
Power = Volts x Amps ( P= V*A) Therefore Amps = P/V in this case .5 amps
Is electrical current greater before or after light bulb?
Electrical current is equal throughout a series circuit.
What is an electric current flowing in only one direction?
In a series circuit, then yes, there is only one pathway. For example: if one bulb fuses, all the bulbs in the serial circuit will go out. But there are more pathways in a parallel circuit. For example: if one bulb fuses, all the other bulbs in the parallel circuit will still light.
What watt fluorescent bulb can you use to replace a 60watt incandescent bulb?
fluorescents are about 5x as efficientso a 12W will give about as much light
What happens when the switch is open in a circuit containing wires a light bulb a switch and a battery?
When you open a switch to a light for example, you cause a break in the flow of current to the light. Opening a light switch means you are turning the light off by stopping the flow of current to it. Closing a switch means you have completed a circuit (basically a loop) and current now flows causing the light to go on. Think of electricity like water. To cause your bath tub to fill up (light on) you have to also complete the circuit by turning the tap. Now we have water flow. (current) To stop the flow of water, we want to open the circuit by turning the tap in the opposite direction causing a break in the flow of water.
What is the current in an ac circuit with 120volts and a 60watt light bulb?
Power = Current * Voltage Current = Power / Voltage Current = 60 W / 120 V Curretn = 0.5 A
What is the current in an AC circuit with a 120-volts and a 60 watt light bulb?
Power = Volts x Amps ( P= V*A) Therefore Amps = P/V in this case .5 amps
If two light-bulbs are connected in a series circuit and one of the light-bulb's current flowing is 0.5 A what is the current flowing in the other light-bulb?
Current in a series circuit is the same throughout the circuit. Voltages are additive. Voltage in a parallel circuit is the same throughout the circuit. Currents are additive.
Is the amount of current that flows in the wire of electric circuit the same as the current that flows in the filament of the light connected in that circuit?
yes
How would the circuit inside a flashlight work?
Flashlight by light, battery, circuit, a hood and a reflective cup, circuit storehouse, switch, etc, the basic principle is the current from the battery, and then to the circuit, after adjusting circuit voltage and current, and then output to the light source for lighting.
What happens in a series circuit if a light blows?
The circuit current is interrupted and all the lights will go out.
This circuit is a series circuit because?
the same current flows through both light bulbs
Why will the current flow be different in a heated rear screen circuit than a side light circuit?
the heated rear screen circuit has a higher resistance compared to the side light circuit
Why is there 0 current when a light bulb burns out?
Incomplete circuit
A light bulb in a simple circuit blows and goes out Is current now flowing in the circuit?
No. Circuit is open but still HOT.
In an electric current electricity flow how?
Electricity can flow in an electric circuit by a battery. The battery creates electrons, which flow through the wire, and then go into a light bulb. (That is how a light bulb in a circuit lights up.) A series circuit is a circuit with one wire that electrons can flow through. Also, there can be more than one light bulb connecting to the same wire. A parallel circuit is a circuit with light bulbs that have their own wire.ClarificationThe above answer, unfortunately, perpetuates the myth that current leaves a battery, and finds its way around a circuit. This is not the case at all. It is the load that 'draws' the current from the battery and it is the load that determines the size of that current.
What happens to lights in parallel if one goes out?
In a series circuit each light completes its part of the circuit and connects to the next light. So, if one light fails, the circuit is broken and the flow of current to all lights must stop.
