Answer 1

Answer:

50 Joules

Explanation:

W= (I)²RT

W = (0.5)²×20×10...........[I = V/T ]

W = 0.25×200

W = 50 Joules.

Answer 2

Answer:

Work done is said to be 1J when 1 C charge is carried in a potential difference of 1V

Potential difference (V)=10 V

Charge(Q)=20,000C

Work done (W)= Q × V

W=20,000×10 J

$W= \: 2 \times {10}^{5} J \:$

So Option (b) is the answer
