Electricity Concepts

Front

What is the potential difference across the ends of a conductor?

Back

The energy transferred per unit electric charge flowing through it.

Front

What does Emf stand for?

Back

The work done per unit charge by the source (battery).

Front

What is terminal potential difference?

Back

The voltage measured across the terminals of a battery when charges are flowing in the circuit.

Front

What is current strength?

Back

The rate of flow of charge.

Front

What is resistance?

Back

The ratio of the potential difference across a resistor to the current in the resistor.

Front

What is the unit of resistance?

Back

One ohm (Ω) is equal to one volt per ampere.

Front

What does Ohm's law state?

Back

The potential difference across a conductor is directly proportional to the current in the conductor at constant temperature.
