الیکٹرک سرکٹ میں بیٹری کو جوڑنے کا مقصد مندرجہ ذیل میں سے کون سا ہے؟

To maintain resistance across the conductor

To vary resistance across the conductors

To maintain constant potential difference across the conductor

To maintain varying potential difference across the conductor

Explanation

A battery is connected in an electric circuit to provide a constant potential difference (voltage) across the circuit, allowing electric current to flow through the conductors.

The battery maintains a constant voltage, ensuring a consistent flow of current through the circuit.
