Vedclass · Answer

(B) The circuit consists of a $12 \, V$ battery,an internal resistance of $2 \, \Omega$,a resistor $R$,and a $4 \, \Omega$ resistor,all connected in series.According to Ohm's Law,the total voltage $V$ is equal to the product of the total current $I$ and the total resistance $R_{eq}$.The total resistance $R_{eq}$ in the series circuit is $R_{eq} = R + 4\,\Omega + 2\,\Omega = R + 6\,\Omega$.Given that the current $I = 1 \, A$ and the voltage $V = 12 \, V$,we have:$V = I 	imes R_{eq}$$12 \, V = 1 \, A 	imes (R + 6\,\Omega)$$12 = R + 6$$R = 12 - 6 = 6\,\Omega$.Therefore,the value of resistance $R$ is $6\,\Omega$.

In the given circuit,find the value of resistance $R$ if the current flowing through the circuit is $1 \, A$.
