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.

What equation relates power to current and resistance?
Power = (current) times (voltage)Current = (Power) divided by (voltage)Voltage = (Power) divided by (current)
What is the relationship between voltage power and current?
The unit of power is watts, the unit of current is amps, and the unit of voltage it volts. Power = Voltage X Current Voltage = Power / Current Current = Power / Voltage In electricity, power is symbolized with a P, current with an I, and voltage with a V. The real formula looks like: P = V x I V = P / I I = P / V
Can you calculate power by multiplying voltage and current?
Not enough information. Power = current x voltage. Since voltage can be anything, there is no way to calculate power. Time is irrelevant; though once you have the power, it can help you calculate energy (energy = power x time).
How do you calculate the current in 40W tube light in 230V?
Voltage x Current = Power So Power / voltage = current Now you do the math
What is the voltage power and current rating of an integrated circuit?
What is the voltage and current of an integrated cicuit
What equation relates power to current and resistance?
Power = (current) times (voltage)Current = (Power) divided by (voltage)Voltage = (Power) divided by (current)
Volt current x power?
No, its Volts x current = power. To be correct its W = I x E where watts = power, I = amps or current and E = electromotive force or voltage.
What is the relationship between voltage power and current?
The unit of power is watts, the unit of current is amps, and the unit of voltage it volts. Power = Voltage X Current Voltage = Power / Current Current = Power / Voltage In electricity, power is symbolized with a P, current with an I, and voltage with a V. The real formula looks like: P = V x I V = P / I I = P / V
How do i fine an expression for power that involves only current and voltage?
You do not need ohm's law to relate power to current and voltage. Power is current times voltage. If you know current and voltage, you do not need to know resistance.
If you multiply the voltage in a circuit by the current what are you going to get for your answer?
Voltage x current = power (watts)
What you get from mains voltage or current?
You get power, which is voltage * current (so both!).
HOW CAN you calculate power if you know the voltage and current?
P = I^2 R = IV = v^2 / R , Where P is power, I is current, R is resistance, and V is voltage. Given voltage and current, power = current * voltage, or P = IV.
How is power and voltage related?
in ac circuits power,P=VICOS@ @ is the angle between voltage and current. in dc P=VI V is the voltage I is the current. Power (in Watts) is current (A) x voltage (V)
What is the power if the resistance is 1.2k and the current is 0.024 ma?
If the resistance is 1.2k and the current is 0.024 ma, then the voltage is 0.0288 volts. (Voltage = resistance times current) If the voltage is 0.0288V and the current is 0.024 ma, then the power is 0.6912 microwatts. (Power = voltage times current)
How can you tell the power and voltage when their is no current?
If there is no current, there is no power.The voltage can be measured with a voltmeter.
What you consume in home current or voltage?
Power is contituted by both current and voltage So we consume both current and voltage
Which component links power and voltage?
current is the other factor. power (wattage) is the product of current (amps) and voltage
