Is it good to do circuit experiment in home? I asked because current is used and we may get shock.
Dear Student,
It is true that while doing electricity experiments, getting an electrical shock is a major concern. Precautions need to be taken appropriately.
Proper insulations and avoiding direct contact to ground reduce most of the shock issues. Our body has an average resistance of 100 k ohms under dry conditions and few hundred ohms under wet conditions.
One should remember that it is the potential difference which is of more concern than the current. This is because total amount of current through you will be decided by the potential difference across you and the resistance of the body. So, while doing low voltage based experiments, like experiments with batteries chances of getting an electrical shock is very less. Because very small current flows through the circuit which becomes further less due to the body resistance.
A current of 2mA can give you a mild shock but not pain. Current values below it is hardly of any concern. But then you cannot control what current will flow through your body. It is the potential difference which decides what current will flow.
Overall I would say with proper insulation you can do low voltage electrical experiments like most of the electronics based experiments at home and avoid doing high current electrical experiments or power electronics experiments at home.
Regards
