Watt is the current allowed to flow through a bulb?
The current flowing through a bulb is equal to the (voltage across the bulb) divided by the (bulb resistance), and can be expressed in Amperes. The rate at which the bulb dissipates energy is equal to (voltage across the bulb) times (current through the bulb), and can be expressed in watts.
What voltage is required to sustain a current of 0.50 through a light bulb resistance of 190?
The voltage of a circuit with a resistance of 250 ohms and a current of 0.95 amps is 237.5 volts. Ohms's law: Voltage = Current times Resistance
What s the correct calulation for the bulb power on watts which has has a current of 0.5 and the voltage is 220v?
Power is current times voltage, so a current of 0.5 amperes and a voltage of 220v across a bulb will yield a power of 110 watts.
Does it matter if the voltage leads the current or the current leads the voltage?
Yes. If voltage leads the current, the impedance is inductive (this would be the case if the load is a motor). If current leads the voltage, the impedance is capacitive (this would be the case for a CFL light bulb).
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.

How much voltage do you give to the zero watts bulb?
230v power supply .................it requires 12watts......
Can you use a 60 watt light bulb in place of a 67 watt bulb?
yes, it can be used - single phase voltage of 230v. 50HZ is important
Why can't a bulb turn on without electricity?
An incadescent bulb lights up because the voltage source creates a current through the filament of the bulb and it heats up because of its composition and gives off light as a result. No electricity, no voltage and no current.
What is the resistance of a 10W bulb?
If you're using it in your home with a voltage supply of 230V [Basically speaking], the resistance would be around 5290Ω. The following equations can help you: P=V*I {Where P is the power, V is the voltage and I is the current} V=I*R {Where R is the resistance}
What is the current through each light bulb in a series circuit?
it remains same i=voltage/total resistance
How many amps are needed to run a light bulb?
If you divide the watts of the bulb by the supply voltage, that is the current. For example a 60 w bulb on a 240 v supply gives a current of 60/240 which is ¼ amp.
What voltage is required a pass 0.5 A of current through a 4.5-W bulb?
9 volts====================The question is a bit convoluted.The power dissipated by the bulb and the current through itboth depend on the voltage applied across it.In the real world, the way to ask this question would have to be:If a light bulb dissipates 4.5 W of power when 0.5 A of currentpasses through it, what voltage has been applied across it ?(And, for extra credit, what is the bulb's effective resistance ?)

What happens when one bulb is added to a series circuit?
The resistance is increased, the voltage across each bulb is decreased and the current through the circuit is reduced.
The light bulb in your lamp has burned out so you replace it with a light bulb with 130 ohms that is plugged into a 100V outlet What is the current flowing through the bulb?
Current = (voltage) / (resistance) = 100/130 = 0.769 A = 769 milliamperes (rounded)
