Question

b) 200J of heat is produced each second in a 5 Ohm resistance. Find the potential difference across the resistor.​

Answer 1

Answer:

H=$I^{2}$Rt

200=$I^{2}$5x1

$I^{2}$=40

I=$2\sqrt{10}$

V=IR=2$\sqrt{10}$x5=10$\sqrt{10}$V

Explanation:

Answer 2

Answer:

potential difference, V=10√10

Explanation:

dH = I^2×R×dt = V^2×dt/R

or, H = V^2×t/R

or, 200=V^2×1/5

or, 200×5=V^2

or, V=√1000

or V=10√10
