✏More about this law...

• 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. ( 1 V = 1 J C-1) Potential difference in a circuit is measured using a voltmeter which is placed in parallel with the component of interest in the circuit.

Answer 2

Answer:

The Potential difference (V) of conductor is 1.67 volts.

Given:

1. Work Done (W) = 5 J

2. Charge (C) = 3 C

Explanation:

_____________________

Potential Difference:

It is defined as work done in bringing a charge from one point to another point is called Potential difference.

It has a Unit of Volts and it is denoted by " V ".

From the formula we know,

⇒ V = W / Q

⇒ V = 5 J / 3 C

⇒ V = 5 / 3

⇒ V = 1.67

⇒ V = 1.67 Volts.

∴ The Potential difference (V) of conductor is 1.67 volts.

Note:

• Symbols have their usual meanings.
