A chemical reaction inside the battery works like a pump to push electricity. The amount of push is the voltage measured in circuit for the electricity to flow round needs to be built of electrical conductors and must provide a loop from the positive to the negative terminal of the battery.
Wire Probes Try touching the ends of the wire probes on to different objects: - your skin - fresh water - salt water - a thick line drawn with a soft pencil - a (non light-emitting) diode (try this with the diode both ways round) M E G A P O W E R 9 V o l t LED Flat & short-lead 220R Probes + +
