Question

220 J of heat is produced each second in a 8 ohm resistor. Find the potential difference across the resistor.​????????​

Answer 1

$\blue{\bold{\underline{\underline{Answer:-}}}}$

HEAT = I²RT

I×IRT

SINCE, V = IR

HEAT = IVT

220 = V/R × VT

220 = V²T/R

220×8/1 = V²

v = $\sqrt{220 \times 8}$

V = 42

Answer 2

H=I²Rt

220=I²×8×1

I²=220/8

I=√220×8

By ohms law we can find the potential difference
