Practical Activity 14-16

Class practical: to measure the current through and potential difference across a lamp as it is switched on.

Practical Activity 14-16

Demonstration: shows that electrostatic charges are the same as the charges passing through wires and components in electric...

Practical Activity 14-16

Demonstration: to some students the feeling for coulombs of charge comes most easily from electrolysis.

Practical Activity 14-16

Demonstration: the electrolysis of water yields oxygen and hydrogen gases and simple calculations estimate the charge of the...

Practical Activity 14-16

Class practical: adding a shunt in parallel with a galvanometer converts it to an ammeter with a higher range. This is a trial...

Practical Activity 14-16

Demonstration: experiments to show that current (and therefore charge) is conserved around a circuit. They can be teacher...

Practical Activity 14-16

Demonstration: a shuttling ping-pong ball serves as a model of ions moving in an electric field.

Practical Activity 14-16

Demonstration: comparisons with magnetic fields may be helpful here.
