Question

When talking about electrical shock in lecture, I told a story of how I was shocked. What household appliance shocked me?

Answer 1

The household appliance that shocked you was likely one with a large short circuit current that could produce a voltage on the appliance's case, such as a grounded toaster, as per Figure 23.57.

Step-by-step explanation:

The household appliance that shocked you was likely one with a large short circuit current that could produce a voltage on the case, even if the appliance was grounded. This is illustrated in Figure 23.57, showing the hazard due to the non-zero resistance of the earth/ground wire. Electrical shock hazards can occur from faulty or damaged appliances, and these shocks can range from mildly painful to lethal, depending on the current. Moreover, thermal hazards like excessive heating from a short circuit or overloaded wires can lead to fires, another serious risk highlighted in the context of household electrical safety.
