Question

If the resistance of your body is $100000\Omega$ what would b the current that flows in your body when you touch the terminals of a 12 V battery?

Answer 1

$\bullet$ From Ohm's law, $V=IR$

$\bullet V=12V;R={10}^5\Omega$

$\bullet$ So when you touch the terminals of the battery, the circuit gets completed and current I will flow

so

$I=\frac{V}{R}=12\times {10}^{-5}A=0.12mA$
