Question

If 2 A current is flowing through the circuit for 2 second when the potential difference between them is 8 volt then find out work done by the charge

Answer 1

Answer:  32J

Explanation:

I= Q/T

2= Q/2

Q= 4 coulomb

V = W/Q

W= V*Q

V= 8v

Q= 4C

W= V*Q

W= 8*4

W= 32 J

Answer 2

$\huge{\mathcal{\blue{\underline{\underline{\pink{HeYa!!!}}}}}}$

${\large{\purple{\mathbb{ANSWER}}}}$

${\large{\blue{\bold{\underline{Given:-}}}}}$

• Current (I) = 2A.

• Time (t) = 2sec.

• Potential Difference (V) = 8V.

${\large{\blue{\bold{\underline{To\:Find:-}}}}}$

• Work done by the charge.

${\large{\blue{\bold{\underline{Now,}}}}}$

▪︎ We know that,

Work done by a charge = Heat released by it in the given time.

▪︎ Also,

Heat (H) = I²Rt.

= I×I×R×t

= V/R × I × R × t.

{Putting I = V/R}

= VIRt/R.

= VIt.

= 8 × 2 × 2.

{By putting Values}

= 8 × 4.

${\large{\red{\boxed{\bold{=\:32\:J.}}}}}$

Therefore 32 Joules of work is done by the charge.
