Class practical: adding a shunt in parallel with a galvanometer converts it to an ammeter with a higher range. This is a trial...
Class practical: a problem-solving activity, using the concept of resistance in the context of a concert sound system.
Class praticals: determining resistance from measurements of potential difference (p.d.) and current.
Demonstration: gases conduct electricity, but they have to be ionised first.
Class practical: an opportunity to measure the electric current and introduce the ampere unit. There is no need to define an...
