Integrated Concepts A short circuit to the grounded metal
Chapter 23, Problem 54(choose chapter or problem)
Integrated Concepts
A short circuit to the grounded metal case of an appliance occurs as shown in Figure \(23.60\). The person touching the case is wet and only has a \(3.00 \mathrm{k} \Omega\) resistance to earth/ground.
(a) What is the voltage on the case if \(5.00 mA\) flows through the person?
(b) What is the current in the short circuit if the resistance of the earth/ground wire is \(0.200 \Omega\) ?
(c) Will this trigger the \(20.0 A\) circuit breaker supplying the appliance?
Figure \(23.60\) A person can be shocked even when the case of an appliance is grounded. The large short circuit current produces a voltage on the case of the appliance, since the resistance of the earth/ground wire is not zero.
