What is active power (P) Active power (P) also known as “real power” or “active power” is the useful power that is used within the AC circuit. What is reactive power (Q) Reactive power (Q) is not used but is transported between the source such as a power station and the loa...
Example of AC waveforms A DC circuit must be connected to the battery’s positive and negative terminals in the proper manner. Some circuits won’t operate properly if the battery is connected backwards. But with a household electrical outlet, electricity will flow even if you reverse the left...

A kilowatt (kW) is a unit of power that measures the rate at which energy is used or produced, while a kilowatt-hour (kWh) is a unit of energy that represents the amount of electricity consumed over time. Essentially, kW indicates the “speed” of energy usage, whereas kWh indicates the...
while both devices provide power to your electronic devices, an ac adapter is plugged into a wall outlet and converts ac power to dc power, while a power bank is a portable battery that stores dc power and can be used to charge your device on-the-go. can i use my laptop without an...

Voltage is also described as the speed of individual electrons as they move through a circuit and is measured in units called volts. In the United States, power from the electrical grid is delivered to homes at two different voltages or "pressures": 120 volts and 240 volts. That's because...
In an AC circuit, the power calculation is not as straightforward. The power is the instantaneous power -- the power at a certain instance of time -- and is represented as the following: P(t) = V(t) x I(t) Instantaneous power changes over time. To calculate the average power value,...
The lower the power factor, the less efficient the circuit, and the higher the overall operating cost. The higher the operating cost, the higher the likelihood that utilities will penalize a customer for overutilization. In most ac circuits there is never power factor equal to one because ...
In an L−C−R ereis circuit R=150Ω,L=0.0750H and C=0.0180μF . The source has voltage amplitude V=150V and a frequencey equal to the resonacne frequency of the circuit. (a) What is the power factor ? (b) What is the average power delivered by the source? (c) The ...
