Three resistors of $\displaystyle 6 \Omega, 4 \Omega$ and $\displaystyle 4 \Omega$ are connected together so that the total resistance is $\displaystyle 8 \Omega$. Draw a diagram to show this arrangement and give reason to justify your answer.
Marking-scheme solution
\[\frac{1}{R_{p}}=\left(\frac{1}{4}+\frac{1}{4}\right)=\frac{2}{4}=>R_{p}=2 \Omega
\]
\(\displaystyle \mathrm{R}=6 \Omega+2 \Omega\)More from Electricity
