Currents

An electric current is the flow or the wave of electricity that moves through a circuit. An electric current can be affected by many things such as resistance,voltage and power. All of these variables can affect currents in multiple ways but the main point of a current is that its the flow of electrons[electricity].

Resisitannce

Resistance is the

difficulty an electric current faces to pass through an object. Resistance affects a current by the more resistance there is there is less of a current. This means with a high resistanc eits hard for a current to pass but with a lower resistance the easier it is for a current. Resistance differs from voltage because with a high voltage there is a higher current unlike resistance which is the opposite. Resistance is mainly just how hard it is for a current to move through an object.

Voltage

Voltage is The potential difference in an electrical charge between two different areas in a circuit. Its the force that makes a current move through the circuit. The more voltage there is the more of a current there is. Basically no voltage = no current. Voltage differs from resistance because with voltage, the more there is of it the more current there is but with resistance its the opposite. Voltage is just the force that pushes the current along the imaginary line of electrons flowing.
