# 4.5: Conductors in Parallel

\(\text{FIGURE IV.3}\)

\[G=G_1+G_2+G_3.\label{4.5.1}\]

That is to say \[\frac{1}{R} = \frac{1}{R_1}+\frac{1}{R_2}+\frac{1}{R_3}.\label{4.5.2}\]

The potential difference is the same across each. The current is greatest through the largest conductance – i.e. through the smallest resistance.
