Voltage: Voltage is the energy that electrons get from a power supply. Voltage is used to make electrical components work, like light bulbs.
Current:Current is the moment of electrons. We measure current using an ammeter. An ammeter measures how many electrons pass it every second. Its is measured in Amps (A).
Aim: To create voltage out of a lemon.
Method
1. Roll the lemon out so the inside is liquid.
2. Stick a piece of zinc and copper into the lemon.
3. connect the lemon up to a voltmeter.
Discussion : When we rolled the lemon we made the inside liquidy. What we did was we freed up all of these acidic charged particles. When its solid, Nothing is moving but when we make a liquid all of the particles move around and create a circuit. When we did it alone the voltage was 0.3 volts. But with the whole class it was 2.3 volts.
