In a circuit, electric charge is carried by tiny particles called electrons. These electrons flow through the circuit when there is a push called voltage, provided by a power source like a battery. Voltage gives energy to the electrons, pushing them to move. The flow of electrons is called current, which tells us how much charge passes through the circuit each second. Resistance is anything in the circuit that slows down this flow, and it depends on the material, length, thickness, and temperature of the wires or components. So, voltage pushes the electrons, current is the flow of electrons, and resistance slows that flow.
V = IR, I = V/R - Ohms law
