Touching a stainless steel table while a plugged-in microwave shocks you because stainless steel is conductive and can allow electric current to flow through it. When the microwave is plugged into an outlet, it is connected to the electrical circuit, which provides power to the microwave. If there is a fault in the microwave or the electrical wiring, such as a damaged cord or exposed wires, it can create a situation where the electrical current is conducted through the table.
When you touch the stainless steel table while it is conducting electricity, you complete the circuit, and the current can pass through your body, resulting in an electric shock. The severity of the shock depends on various factors, such as the current strength and the duration of contact.
It's important to note that the shock hazard is not specifically related to the stainless steel table itself, but rather to the electrical fault in the microwave or the wiring. If there are no issues with the microwave or the outlet, touching a stainless steel table should not shock you. However, it's always a good idea to ensure that your electrical appliances and wiring are in good condition to minimize the risk of electric shocks. If you experience electrical shocks while using any appliance, it's essential to have it inspected and repaired by a qualified electrician to ensure your safety.
