Homework Statement
Suppose that a person's body resistance is 900ohms.
a) what current passes through the body when the person accidentally is connected to 110V?
b) if there is an alternative path to ground whose resistance is 40 ohms, what current passes through the person?
c) if the voltage source can produce at most 1.5A, how much current passes through the person in case b)?
Homework Equations
V=IR
The Attempt at a Solution
A) V=IR, I=0.122
B)1/900+1/40=0.026^-1=38.29 ohms, 110/38.29=2.87amps, 0.122a passes through the person, 2.75amps passes through the ground
C) Would the answer just be 1.372amps since 2.75-1.5=1.25 and then 1.25+0.122=1.372?
