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
What is meaning oof rated values of current voltage power and torque of an electrical machine?
What it means is that those rated values may not be exceeded, they are the maximum that the machine can take.
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 apparant power?
Apparent power is the combined power value that is obtained by allowing for the different values of current and voltage.
What is the significance of negative values of voltage and current in the digital VOM?
The significance of negative values of voltage and current in the digital VOM is to show the accurate and full power that a particular device or equipment has in the result.
What equation relates power to current and resistance?
Power = (current) times (voltage)Current = (Power) divided by (voltage)Voltage = (Power) divided by (current)

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.
Why do the readings differ for increasing and decreasing values of the incandescent lamp voltages?
...what readings? current? voltage? power? lux?
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)
What is meaning oof rated values of current voltage power and torque of an electrical machine?
What it means is that those rated values may not be exceeded, they are the maximum that the machine can take.
