Electric circuits #3 What's wrong here? in the manual.
If we wanted an indicator light to tell whether the toaster is
on, we could use a parallel circuit or a series circuit
The heater in a toaster is just a resistor. It's actually a
rather low resistance, so that a big current flows and lots of
power is turned into heat. Look inside your toaster, and you will
see these wires -- they look quite a bit like the diagram!
The red circle indicates where the indicator light is to be
placed in each circuit. What are the advantages of each design?
If there is something that you don't understand about electrical
circuits, Ask us!
