resistance

     Resistance is the resistance of an object to the passage of current, and the unit of resistance is ohms (Ω, Ohm)

Electric power

     The electrical power of a circuit refers to the electrical energy that the circuit transmits per unit of time. Like mechanical work, electrical power is the rate at which work is done. Using the International System of Units, the unit of electrical power is Watt. If a circuit transmits 1 joule of electrical energy per second, then the electrical power is 1 watt.

     In a DC circuit, the electrical power of an element is the current through the element times the voltage across the element. If the current is 1 amp and the voltage is 1 volt, then the electrical power is 1 watt.

     In AC circuits, current and voltage change over time. The instantaneous power of an element is the electrical power absorbed by the element at a particular moment, and is the instantaneous current through the element multiplied by the instantaneous voltage across the element. Since the instantaneous power also changes over time, it is difficult to make actual measurements. The easier one to measure is the average power; this is the average of the instantaneous power over an AC cycle and is equal to the apparent power multiplied by the power factor. Apparent power is the product of rms current and rms voltage. The power factor is the cosine of the phase difference between the current and the voltage; if the power factor is 1, the load of the element is called a purely resistive load, which absorbs electrical power at all times; if the power factor is 0, the load of the element is called It is a pure reactive load, and the absorbed electric power is 0 after time average.
