FLASHCARD QUESTION

Front

What is current in an electrical circuit?

Back

Current is the flow of electric charge, typically carried by electrons in a conductor.

2.

FLASHCARD QUESTION

Front

What unit is used to measure current?

Back

The unit of current is the Ampere, often shortened to 'Amp' (A).

3.

FLASHCARD QUESTION

Front

What is voltage?

Back

Voltage, or electric potential difference, is the force that pushes electric charges through a circuit.

4.

FLASHCARD QUESTION

Front

What unit is used to measure voltage?

Back

The unit of voltage is the Volt (V).

5.

FLASHCARD QUESTION

Front

What is resistance in an electrical circuit?

Back

Resistance is a measure of how much a material opposes the flow of electric current.

6.

FLASHCARD QUESTION

Front

What unit is used to measure resistance?

Back

The unit of resistance is the Ohm (Ω).

7.

FLASHCARD QUESTION

Front

What is Ohm's Law?

Back

Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R). It can be expressed as V = I × R.
