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.
If you unscrew a light bulb slightly and leave the power on to it is it still using power?
Possibly. If it still works when you turn it on, the of course it is using power. If it does not work when it otherwise would, then it is definitely not using power, just as if you didn't have the bulb there at all. <<>> With the voltage on the circuit and the light bulb in the circuit, the bulb will glow. If you unscrew the bulb until it goes out the potential voltage will still be in the circuit but no current will flow so no power will be used. In this scenario the unscrewing of the bulb will be the same as using a switch in the circuit to interrupt the current flow.
What are the uses of the light bulb?
A bulb is not necessary in a circuit. A circuit is simply a series of connections that allows current to flow. A bulb, or a resistor, or something else, is simply a way to do useful work with that current flow, in the case of a bulb, converting power to light and heat.
Will the bulb light if the filament is broken Why?
No, the broken filament breaks the connection which electricity needs to complete the 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 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
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.
What is the Current through a 75-watt bulb that is connected to a 120-volt circuit?
Considering an incandescent bulb and using P=VxI P= Power Watts V= Volts I= Current (amperes) I=P/V I=75Watts/120Volts = 0.625 Amperes (A or Amps) Therefore the current through a 75watt bulb that is connected to a 120volt circuit is 0.625 amps.
Why is there 0 current when a light bulb burns out?
Incomplete circuit
How do you know when electric current is flowing in a light bulb circuit?
You know if current is flowing in a bulb circuit because, if there is enough power (voltage times current), the bulb will illuminate. If there is current, but not enough power to illuminate the bulb, you will need to measure the current with an ammeter to see if there is any current.
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.
How much resistance does a light bulb create if it has a current of 25 mA around it in a 9 V circuit?
how much resistance does a light bulb creat if iyt has a current of 25 mA around it in a 9 V circuit?
Based on what you have seen what must be true for a circuit to light a bulb?
There must be a current through the bulb in order for it to glow.
Is electrical current greater before or after light bulb?
Electrical current is equal throughout a series circuit.
Is circuit part of a light bulb?
A light bulb can be part of a circuit.
What gives out a light if an electric current flows through it?
A light bulb in an electric circuit when electricity reaches it.
What happens when one light bulb goes out in a series?
The failed bulb breaks the circuit so no current can flow - so the other bulb goes out (but is OK).
