Yep. This is because the device needs the battery in order to work.
no as the battery is made of metal and metal conducts electricity
Yep. This is because the device needs the battery in order to work.
For it to meaningfully to be a circuit, electrons must flow round the complete circuit. Thus a source of energy is needed, be it a battery, or the mains electricity.
The form of potential energy inside of a battery is electrical energy travel inside the circuit. It takes cells inside the battery don't recharge, the cells are dead.
Till your battery runs dead.
You would have a open circuit. It would appear dead.
A Light bulb lights in a complete circuit because then the electricity from the battery can travel round the wire that has no breaks. BUT the switch has to be close. Z
The conducting path of a torch is a simple circuit: Battery to switch, switch to bulb, bulb back to battery. Provided the switch is on, and there are no breaks in the circuit wiring (and the bulb is good), the torch should work.
A dead short occurs which can result in the battery exploding A completion in the external circuit of the battery
The purpose of the battery in a circuit is to wive energy to the circuit
When that circuit has no breaks. It is an endless path of current flow.
