- Potential difference: The difference in electric potential between two points in an electric circuit. It is measured in volts (V) and is commonly referred to as voltage. The symbol for potential difference is V.
- Current: The flow of electric charge in a circuit. It is measured in amperes (A) and is commonly referred to as current. The symbol for current is I.
- Resistance: The opposition to the flow of electric current in a circuit. It is measured in ohms (Ω) and is commonly referred to as resistance. The symbol for resistance is R.
- Abbreviation units:
- volts: V
- amperes: A
- ohms: Ω
