Question

how potential difference is measured

Answer 1

Hey mate here is ur answer .......

Potential difference is measured in volts by using the device called voltemeter.

Hope it helps♥

Answer 2

HEYA!!!


HERE IS YOUR ANSWER,


> Potential difference is the work done per unit charge.

> A potential difference of 1 V means that 1 joule of work is done per coulomb of charge.

> Potential difference in a circuit is measured using a voltmeter which is placed in parallel with the component of interest in the circuit.

=> V = W/Q

> V : Potential difference, W : Work done, Q : Charge.

> When a voltmeter is connected across a resistor, say, the voltage present across that resistor is then also connected to the voltmeter.

> This produces a small current through meter that causes the needle of the instrument to indicate.

> The higher the voltage the more current flows and the meter will read higher.
