Power is another term for watts. It is the product of amps flowing in the circuit, times the voltage in the circuit. The amount of power the circuit consumes is governed by the resistive or inductive load.
The components in the electric circuit get their operating power from the power supply,
if there is one. The power supply, if there is one, gets the energy to operate the circuit
from one of the following sources:
-- battery, fruit, potato, etc. (stored chemical energy)
-- photovoltaic cell (solar cell)
-- wind (captured by a windmill)
-- plug inserted into an outlet in the home, delivering energy from the public utility company,
which gets the energy from one of the following:
. . . . . burning coal to boil water to spin a generator
. . . . . burning oil to boil water to spin a generator
. . . . . burning natural gas to boil water to spin a generator
. . . . . capturing the heat from radioactive decay of uranium to boil water to spin a generator
. . . . . focusing the sun onto a water pipe to boil water to spin a generator
. . . . . holes dug deep into the ground to capture heat from the earth to boil water to spin a generator
. . . . . water wheels stuck into waterfall to spin a generator
. . . . . photovoltaic cells (solar cells)
. . . . . wind (captured by windmills) to spin a generator
a battery
A device or circuit that provides power to the rest of the circuit or system is called a power supply,
power factor=real power/apparent power... real power in the sense the capacity of the circuit for performing a work in a particular time..for example the work done by a motor circuit is so and so...real power is what we consume from them... apparent power if the product of the current thro' the circuit and the voltage...it will be always greater than the real power.. if the POWER FACTOR IS 1.0(100%),THEN THE AC POWER IN THE CIRCUIT WILL BE EQUIVALENT TO THE POWER OFFERED BY A DC CIRCUIT....
The power factor of a purely resistive circuit is 1.0.
The energy comes from an additional power source, like a battery. Via various resistors and capacitors, the energy from the power source is put into the circuit. The signal that enters the ciruit will exit the circuit with a higher energy; the signal has been amplified.
A resistor doesn't have a power factor. However, if a circuit is pure resistance in nature the power factor will be one when a voltage is applied and a current flows in the circuit. The power factor is a measure of the relative phases of the current and voltage in a circuit.
wires that come back their point of origin, usually a power supply.
Check the circuit breakers.
The Three sources of power for control circuit are dynamic power, short-circuit power and leakage power.
A device or circuit that provides power to the rest of the circuit or system is called a power supply,
It depends what circuit you are making.Circuit breakers come in different 'ratings' and so are chosen according to the power demands of the circuit you have.You don't choose a circuit for a circuit breaker as such, you choose a circuit breaker according to what circuit you have made.
Electrons in a covalent bond come from the highest occupied energy level.
The load that is connected to the circuit is what draws the power of the electrical circuit.
Power = (energy used)/(time to use it)Power dissipated by an electrical circuit =(voltage across the circuit) x (current through the circuit)or(resistance of the circuit) x (square of the current through the circuit)or(square of the voltage across the circuit)/(resistance of the circuit)

There are many terms that do not represent electric power in a circuit, such as cauliflower, aeroplane and rabbit.Electric power in a circuit is measured in watts (W).
To provide power for the circuit.
