Question

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

Answer 1

GiveN :

• Current (I) = 0.5 A
• Potential Difference (V) = 6 V
• Time (t) = 1s

To FinD :

• Work Done

SolutioN :

We know that,

⇒V = W/Q

and I = Q/t

⇒V = W/(It)

⇒W = VIt

⇒W = 6 * 0.5 * 1

⇒W = 3 Joules.

Work Done is 3 Joules, and we know that energy is stored in Work Done. So energy transferred is 3 Joules.
