Arefe Naderlouei The diagram shows a potentiometer circuit used to compare the electromotive forces (e.m.f.), $E_1$ and $E_2$, of two cells.
$XY$ is a uniform resistance wire. The fixed resistor has resistance $R$.
A sliding contact is moved along the wire $XY$. When the sliding contact is at position $P$, the galvanometer reads zero.
The circuit is changed so that the galvanometer reads zero when the sliding contact is at a new position to the left of $P$.
Which change could…
