A method which does not appear in any of the text-books

4(2) Physics Hints & Tips

4(2) Charge and potential

A  demonstration of fundamental importance in electrostatics, in the way in which it illustrates the relationship between charge and potential, and incidentally teaches that a GLE measures potential and not charge.

5(3) Hysteresis loop

We give the circuit for showing hysteresis loop on an oscilloscope.

6(4) Adapting meters

As there are advantages in using the same instrument for all pupil work, we give below the use of wire length required to shunt this instrument for various currents.
