Mr Amp: Current Analogy for Electric Circuits

Overall rating 5 out of 55 (4 ratings)

Last updated 17 June 2014, created 05 January 2013, viewed 2,619

KS3/4 children can struggle with the concepts of current and voltage, and with how to correctly connect an ammeter/voltmeter. I tried this analogy: current is like the number of children running through a corridor /sec: Mr Amp (the ammeter) stands in the corridor counting children (electrons) and ti More…ming them (this explains why the ammeter is wired in series). This can help in showing conservation of current around the circuit and explain observations in parallel vs series circuits. Also contains a slide of investigations to complement it. See also: Mrs Volt (chocolate biscuits and voltage)!
