A potato can produce an extra current that came from 3v batttery and design it then can post it through person's body.. Here a person is the component of a circuit such as switch.
HERE WE GO
HOW TO CONNECT
1. component; digital clock, copper wire, zinc plate, and copper plate
2. connection; connect a copper wire from positive and negative terminals of the digital clock
then conect the negative terminal wire to a copper plate and point into the dry uncooked irish potato; Then connect the positive terminal wire to a negative terminal of the battery and other wire from positive terminal of the battery to the zinc plate;.
3. switching; then the circuit is not complete there is a switch we need to on a digital clock, you know what is that?. it's a person and here we can use more than ten persons that the first person touch a potato and the last person touch the zinc plate,then they and other more than eight persons touch each other THEN A CLOCK WILL START!!!
NB
1. Whenever a person leave a touch a clock stops to indicate circuit is broken2. The more person the more energy is needed i.e 3v,4.5v, even 9v
3. An error mightly happen in clock connection it need an extra knowledge in wire connection
4. Any miss connection disscourage the circuit.
