Take a long wire and connect it to one end of the out put terminal

Connect the other terminal of the transformer
To the other terminal of the battery

When the actual input of the transformer is touched on someone and then touch the longer wire to the small metal piece the person gets shock

When the current goes to the transformer it increases and when we touch the longer wire to the small metal piece the circuit completes and the person touching the other terminal of the transformer gets a shock
