a.) What current passes through the body when the person accidentally is connected to 220 V?
I know the answer to this question is 0.239 A, but the next two, I do not. That's where you come in!
b.) If there is an alternative path to ground whose resistance is 46 ohms, what current passes through the person?
I don't know what happens when there is resistance in the ground...
c.) If the voltage source produces 1.5 A, how much current passes through the person in case (b)?
Please help. Thank you.

b) Can't tell for sure - is the 46 ohms in parallel with the 920 ohms? Seems like, alternate path... If so, the body still has 220 V across it and the same current through it.
c) 0.239 A

a) 220 / 895 = 0.246 A b) a million/(a million/40 six + a million/895 ) = entire res = 40 3.seventy 5 entire modern = 220/40 3.seventy 5 = 5 A modern by way of physique = 5*40 six/(40 six+895) = .244 A c) a million.5*40 six/(40 six+895) = .0.33 A
