How To Connect A Bulb To A Battery. Try this very interesting way of testing a light bulb and a battery. Battery and Bulb Experiment.
Try this very interesting way of testing a light bulb and a battery. Electrical elements less awkward. I try to cover all the possible cases that you might encounter.
If the battery is 12V and the light bulb only draws 3V the resistor would be required to drop 9V.
When you connect the two wires to the light bulb it will light up source. You can use some kind of circuit so that the output from that circuit is a constant voltage irrespective of the changes at the input side solar panel. Connect the battery to be sure that all bulbs operate in the circuit you assembled in Step 1. About the size we all used in science at school.
