Vedclass · Answer

(B) Given: Heat produced $H = 100 \, J$,Resistance $R = 4 \, \Omega$,Time $t = 1 \, s$.We know that the formula for heat produced is $H = I^2 R t$.Rearranging to find current $I$:$I = \sqrt{\frac{H}{R t}} = \sqrt{\frac{100}{4 	imes 1}} = \sqrt{25} = 5 \, A$.Now,using Ohm's Law to find the potential difference $V$:$V = I 	imes R$$V = 5 \, A 	imes 4 \, \Omega = 20 \, V$.Therefore,the potential difference across the resistor is $20 \, V$.

Sample	$A$	$B$	$C$
Resistivity	$1.6 \times 10^{-8} \Omega \cdot m$	$5.2 \times 10^{-8} \Omega \cdot m$	$100 \times 10^{-6} \Omega \cdot m$

$100 \, J$ of heat is produced each second in a $4 \, \Omega$ resistance. Find the potential difference across the resistor. (in $, V$)
