Resistance and Ohm's Law

This set of flashcards covers key vocabulary and concepts related to resistance and Ohm's law in electrical circuits.

Potential Difference

Energy per unit charge, measured in volts (V).

Ohm's Law

the current is directly proportional to the potential difference at a constant temperature

Resistance

Opposition of a wire to the flow of electricity, measured in Ohms (Ω).

Charge (Q)

The amount of electricity measured in coulombs (C).

Internal Resistance

Resistance within a battery that causes energy loss, affecting terminal voltage.

Power (P)

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

Energy Units (E)

Measured in kilowatt-hours (kWh), representing energy consumption.

Electromotive Force (emf)

Energy converted to electrical energy per unit charge, measured in volts.
