True or False:
1. A voltage supply of 240 V combined with a skin resistance of 2M\Omega is likely to result in a very dangerous electric shock.
2. The master switch in a house turns off the voltage but leaves the current still able to flow.
How should I approach question 1?
and also, what does a master switch do?
