How much current would a 15W light bulb draw if it had 120 volts applied to it?

Basically,
Power = Current*Voltage
Current = Power/Voltage
Current = 15/120
Current = 0.125A or 125mA

Is 123.4 volts acceptable for house current?
Volts would be tension, not current. And if it's acceptable or not depends on what tension you're supposed to have.
Would current of 126 volts be detrimental to your appliances that are rated for 120 volts?
yes, 126 is a little high.. 1 or 2 volts ok
What would 7.5 volts do to a person?
It depends... If the voltage were applied externally, like to fingers or toes, etc. basically nothing. If the voltage were applied to the tongue, you would feel a tingling sensation, nothing more. If it were applied with electrodes inserted through the chest directly to the heart muscle, it could stop your heart, killing you! It's not the volts that cause damage or pain, its the amps. The higher the voltage, the higher the amps. Also, if the electrodes touch moist tissue such as your tongue, the saline moisture conducts better, causing higher current. If the current gets high enough, tissues start to heat, and enough can cause tissue destruction. 7.5 volts is not high enough to do that, given the resistance of human tissue. But, even low current, if it flows through a muscle, can cause the muscle to contract uncontrollably. This is why even a small current through the heart is trouble. Unless you deliver the current directly to the heart muscle, it takes much higher voltage. If you grab an electrode with each hand, for instance, some current would flow through the heart, but because the skin resistance is so high, it takes several dozens of volts before the heart would be endangered.
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
How many watts can can you use with a 20 amp 110 volt outlet?
If you are asking about 220 watts, remember Watts equal power, which is Volts times Amps. Amps are used to measure current - how many electrons flow past a certain point per second - so there is no answer to this question. If you meant to ask what current a load of 220 Watts would take if the applied voltage was 110 Volts, the answer is 220 Watts divided by 110 Volts = 2 Amps.
How much current would an applied voltage of 10 volts cause through a resistance of 5 ohms?
10 volts applied to 5 ohms would cause a current flow of 2 amperes. Current = voltage divided by resistance.
A circuit has an applied voltage of 100 volts and a resistance of 1000 ohms What is the current flow in the circuit?
A circuit has an applied voltage of 100 volts and a resistance of 1000 ohms. The current flow in the circuit is 100v/1000ohms which would equal .1.
How much current would an applied voltage of 60 volts?
Can't tell without knowing resistance.
How any volts are produced in a circuit with 40 amp's of current flowing through a wire with 5 ohms of resistance?
It is a voltage (potential) applied to a load that causes a current to flow through the load. Ohm's Law encapsulates this principal and states Volts = Current x Resistance. In your example, the applied voltage would be 200 volts.
Discuss the series operation of LASCR?
You would get output when the intensity of the applied light is higher and series current would make the current amplitude higher.

How do you calculate the current?
If the wattage of a load is known then the current can be calculated. Watts equals amps times volts. You would use the following formula, Amps = Watts/Volts.
How many watts is five volts?
It depends on the current in amps. The watts would be equal to 5 times the current, because watts equals amps times volts.
A light draws current of 1.1 amps at 230 volts the power onput is 200w what is the circuit power factor?
The current's power factor is the true power divided by the apparent power. The Apparent Power is the volts multiplied by the amps. In this example, the ratio would be 200/253, or approximately .79.
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 ?)
