Question

A 5.0 amp current is setup in an external by a 6.0 volt storage battery for 6.0 minutes. The chemical energy of the battery is reduced by ....

• A. $1.08\times10^4 \,J$
• B. $1.08\times10^4 \,volt$
• C. $1.8\times10^4 \,J$
• D. $1.8\times10^4 \,volt$

Answer 1

Answer: (A)

$1.08\times10^4 \,J$

Answer 2

Work done = V I $t$ = 6 $\times$ 5 (6 $\times$ 60) = $1.08 \times 10^4$ J
