Definition

Electric current refers to the flow of electric charge in a conductor, such as a wire. It is measured in amperes (A) and represents how many charges pass through a point per unit time.

Resistance:

Resistance is a property that opposes or restricts the flow of electrical current in a circuit. It is measured in ohms (Ω).

Ohm's Law:

Ohm's Law states that there is a direct relationship between voltage (V), current (I), and resistance (R) in a circuit: V = I * R.

Power:

Power is the rate at which work is done or energy is transferred in an electrical circuit. It is measured in watts (W) and can be calculated as P = V * I, where V is voltage and I is current.
