Vedclass · Answer

(D) According to Ohm's law,the equivalent resistance $R$ required for the circuit is given by $V = I R$,which implies $R = V / I$.Given supply voltage $V = 220 \,V$ and current $I = 5 \,A$,the required equivalent resistance is $R = 220 / 5 = 44 \,\Omega$.When $x$ resistors of resistance $r = 176 \,\Omega$ are connected in parallel,the equivalent resistance $R$ is given by $1 / R = x / r$.Substituting the values,we get $1 / 44 = x / 176$.Solving for $x$,we get $x = 176 / 44 = 4$.Therefore,$4$ resistors of $176 \,\Omega$ are required.

How many $176 \,\Omega$ resistors (in parallel) are required to carry $5 \,A$ on a $220 \,V$ line?
