What is Volt (V)? Unit of Electrical Potential and Voltage What is Ampere (A)? Unit of Electrical Current & Calculation What is Ohm (?)? Unit of Electrical Resistance and Impedance Quiz

Volt (V) — Voltage is the potential difference, measured in Volts (V).

Electrical Current — Ampere (A) measures the flow of electrical current.

V = I * R — Ohm's Law states that Voltage (V) = Current (I) * Resistance (R).

Ohm (?) — Resistance to the flow of current is measured in Ohms (?).

6 ? — Using Ohm's Law (R = V/I), 12V / 2A = 6?.
