Electric power is simply the amount of power consumed by or generated by a device. It depends on the applied or generated voltage and the current flow.
The larger the value in amperes, the more electricity is flowing in the circuit. Electricity is easy to visualize if you think of it as the flow of water in a river (See Fig.1). Particles called electrons come together, and the number of electrons flowing each second is the current. ...
Electric power is the rate of energy consumption in an electrical circuit. The electric power is measured in units of watts.

If you connect a miniature bulb to a battery, the bulb will generate a uniform amount of light as long as there’s power remaining in the battery, and that is a characteristic of direct current. Direct current flows in a flat or pulsating waveform. Example of DC waveforms By contrast, al...
OK, now ask yourself this: when "electricity" is flowing, is it called an Electric Current? Yes? If so, then "electricity" is simply the charges already inside the wires, where a flow of electricity is a flow of charge. And therefore we must say that the "electricity" sits inside ...
Electric Potential (Energy) When we harness electricity to power our circuits, gizmos, and gadgets, we're really transforming energy. Electronic circuits must be able to store energy and transfer it to other forms like heat, light, or motion. The stored energy of a circuit is called electric...
The unit for current is the ampere (A). Mathematically, the flow rate of charge with respect to time can be expressed as, In other words, a stream of charged particles flowing through an electrical conductor or space is known as an electric current. The moving charged particles are called ...
The force that acts on the electrons is called and electromotive force, or EMF, and its quantity is voltage measured in volts.Electron flow under the action of applied electro-motive force To gain a little more understanding about what current is and how it acts in a conductor, it can ...
How do we measure an electric current? An Ammeter is an instrument use to measure current.(IMGE NEEDED(. The ammeter The ammeter measures the number of electrons that go through the meter each second. Current is measured in units called amperes. To use an ammeter you put the meter in ser...
