Question

A battery of 10 Volt carries 2.5 ampere of current through a resistance of 0.2 Ohm. The work don one minute is: a)1500 J b) 0.5 J c)25J d) 1.250 J Which one of the below circuit is properly connected with the electrical com​

Answer 1

• Current=I=2.5A
• Resistance=0.2ohm
• Time=1min=60s

We know

$\boxed{\sf Work\:Done=I^2Rt}$

$\\ \sf\longmapsto Work\:Done=2.5^2\times 0.2\times 60$

$\\ \sf\longmapsto Work\:Done=6.25\times 12$

$\\ \sf\longmapsto Work\:Done=75J$
