Solution 1
(d) 3 J / s
Electrical energy transferred per second,
`E=V xx I xx t =6Vxx0.5Axx1s=3 "J/s"`
Solution 2
(d) 3 J / s
Electrical energy transferred per second,
`E=V xx I xx t =6Vxx0.5Axx1s=3 "J/s"`
Solution 3
(d) 3 J / s
Electrical energy transferred per second,
`E=V xx I xx t =6Vxx0.5Axx1s=3 "J/s"`
Solution 4
(d) 3 J / s
Electrical energy transferred per second,
