A \(5.0\) A current is setup in an external circuit by a \(6.0 \mathrm{~V}\) storage battery for \(6.0 \mathrm{~min}\). The chemical energy of the battery is reduced by
- A \(1.08 \times 10^{4} \mathrm{~J}\)
- B \(1.08 \times 10^{4} \mathrm{~V}\)
- C \(1.8 \times 10^{4} \mathrm{~J}\)
- D \(1.8 \times 10^{4} \mathrm{~V}\)
Answer & Solution
Correct Answer
(A) \(1.08 \times 10^{4} \mathrm{~J}\)
Step-by-step Solution
Detailed explanation
Given, \(I=5 \mathrm{~A}, V=6 \mathrm{~V}, t=6 \mathrm{~min}=6 \times 60=360 \mathrm{~s}\) Heat produced in a circuit =Chemical energy reduced in the battery \(\Rightarrow\)…
