Tin connected​

Answer 1

Answer:

Explanation:

Given :

• Electric charge (Q) = 1.5 C
• Work done (W) = 9 j

To Find :

• The potential difference across the wire.

Formula to be used :

• V = W/Q

Solution :

Potential difference,

V = W/Q

⇒ V = 9/1.5

⇒ V = 6 V

Hence, The potential difference across the wire is 6 V.
