Question

A 5.0 μF capacitor is charged to a potential difference of 800 V and discharged through a conductor. The energy given to the conductor during the discharge is (A)  1.6 × 10−2 J  (B) 3.2 J (C) 1.6 J (D) 4.2 J

Tardigrade Admin · Accepted Answer

Energy given to conductor =(1/2) C V2 =(1/2) × 5 × 10-6 ×(800)2 =1.6 J

Q. A $5.0 μ F$ capacitor is charged to a potential difference of $800 V$ and discharged through a conductor. The energy given to the conductor during the discharge is

$1.6 \times 1 0^{- 2} J$

3.2 J

1.6 J

4.2 J

Energy given to conductor $= \frac{1}{2} C V^{2}$
$= \frac{1}{2} \times 5 \times 1 0^{- 6} \times (800)^{2}$
$= 1.6 J$
