You have a typical resistance of 100k.
How much current could a 12-V car battery pass through you?
I= A

A watch uses energy at the rate of 260 W

How much current does it draw from its 1.5 Vbattery?

I= mA

Current, I = V/R

where

V = voltage

R = resistance

So, I = 12/(100*10^3)

So, I = 1.2*10^-4 A <-----answer

Rate of use of energy,

P = 260 uW

V = 1.5 V

Now, P = V*I

So, I = P/V = 260*10^-6/(1.5) = 0.173 mA
