Electromagnetic induction is the process of generating electric current by moving a conductor in a magnetic field or by changing the magnetic field.

Solar panels generate electricity by converting sunlight into direct current (DC) electricity. This is achieved using photovoltaic (PV) cells.

Batteries come in all shapes and sizes and are used for various purposes. The different types include alkaline, lithium-ion, nickel-cadmium, and lead-acid.

Batteries convert stored chemical energy into electrical energy. This is done by transferring electrons from one material to another.

Electrical power can be calculated by multiplying voltage by current. The resulting unit is measured in watts, and signifies the rate of energy transfer.

An electrical circuit is a closed loop of conductive materials that allows electricity to flow through it. It can contain various components such as bulbs, switches and resistors.

Series and parallel circuits are two types of electrical circuits. Series circuits have one path for current while parallel circuits have multiple paths.

Ohm’s Law is a fundamental principle in electrical engineering that describes the relationship between voltage, current, and resistance in a circuit. By understanding this law, you can determine how much current flows through a circuit and how much power it consumes. Ohm’s Law is essential for designing and troubleshooting electrical systems, making it a critical concept for anyone working with electronics.

Electric current flows in a circuit due to the movement of electrons from a high potential to a low potential, creating a continuous flow of energy.

Electrical resistance is a measure of how much an electrical component opposes the flow of electric current. It is measured in Ohms (Ω).
