Question

How many joules of electrical energy are transferred per second by a 6 V; 0.5 A lamp? 

(a) 30 J/s
(b) 12 J/s
(c) 0.83 J/s
(d) 3 J/s

Answer 1

(d) 3 J / s
Electrical energy transferred per second,

`E=V xx I xx t =6Vxx0.5Axx1s=3 "J/s"`

Answer 2

(d) 3 J / s
Electrical energy transferred per second,

`E=V xx I xx t =6Vxx0.5Axx1s=3 "J/s"`

Answer 3

(d) 3 J / s
