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 wattless current?
wattless current means that current by which no power is dissipated (Power=0).
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 AC power and DC power?
AC Power is Alternating Current whereas DC Power is Direct Current.
How would you relate power to current?
Power is directly-proportional to the square of the 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.
How the current are related to the power supplied by the source?
Power (watts) is voltage times current.
What is current purchasing power accounting method?
What is current purchasing power accounting method
Is current reduces with increase in powerfactor?
If power factor is increased, current will be reduced for a specific real power (kWs) relative to before. Total power is real power plus the vector of reactive power (you have to do polar math). So total current = (current from real power) + (current from reactive power). By changing the power factor, you decrease the second quantity. Go to Wikipedia.com and search for Power Factor if you need a more extensive description.
Do devices operate on power or current?
Electrical devices use power to operate, but power does not exist without current. Alternately, if current is flowing, power is being stored or used by some electrical device.
What is the formula for power in terms of amperes?
Electrical power = current x voltage Current is in amps
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)
