Ohm's Law

Describes the relationship between voltage, current, and resistance.

Voltage (V)

The electric potential difference measured in volts.

Current (I)

The flow of electric charge measured in amperes (A).

Resistance (R)

Opposition to the flow of current, measured in ohms (Ω).

Ammeter

A device used to measure current, connected in series.

Voltmeter

A device used to measure voltage, connected in parallel.

Ohmmeter

A device used to measure resistance of an isolated resistor.

Power (P)

The rate at which electrical energy is transferred, measured in watts (W).

P = VI

Formula to calculate power, where P is power, V is voltage, and I is current.

Ohm's Law Triangle

A visual aid for remembering the relationship between voltage, current, and resistance.

V = IR

Formula defining Ohm's law, relating voltage, current, and resistance.

P = I²R

Formula for calculating power using current and resistance.

R = V/I

Formula for calculating resistance based on voltage and current.
