In a moving coil galvanometer, why is the magnetic field made radial?
(ii)
You are provided with one low resistance $R_L$ and one high resistance $R_H$ and two galvanometers, $G_1$ and $G_2$. Draw diagrams to show how you will convert $G_1$ to a voltmeter and $G_2$ to an ammeter.
Draw: circuit diagrams showing conversion of $G_1$ to a voltmeter and $G_2$ to an ammeter
Must show: galvanometer $G_1$ in series with high resistance $R_H$, galvanometer $G_2$ in parallel with low resistance $R_L$ (shunt)
