Back

Battery.

Front

What is the difference between a series circuit and a parallel circuit?

Back

In a series circuit, components are connected end-to-end, while in a parallel circuit, components are connected across common points, allowing multiple paths for current.

Front

What is the unit of electrical energy?

Back

Joule (J).

Front

What device is used to measure electric current?

Back

Ammeter.

Front

What is Ohm's Law?

Back

The relationship between voltage (V), current (I), and resistance (R) in a circuit, expressed as V = I × R.

Front

What is the role of a resistor in a circuit?

Back

To limit the flow of electric current.
