Question

So that your grandmother can listen to A Prairie Home Companion, you take her bedside radio to the hospital where she is staying. You are required to have a maintenance worker test the radio for electrical safety. Finding that it develops 120 \mathrm{~V} on one of its knobs, he does not let you take it to your grandmother's room. Your grandmother complains that she has had the radio for many years and nobody has ever gotten a shock from it. You end up having to buy a new plastic radio.(a) Why is your grandmother's old radio dangerous in a hospitals

Answer 1

The old radio will not be safe in a hospital and buying a new one is the best thing to do as to prevent the risk of her or other individuals getting electrocuted.

What is Voltage?

This is referred to as the difference in electric potential between two points or the work done which is needed per unit to move a charge between two points in a circuit.

All individuals have varying skin resistance which is why exposure to that radio which develops 120V on one of its knobs may lead to electrocution or other types of injuries to the grandma or other individuals in the hospital.

This is therefore the reason why the old radio will be dangerous in a hospital environment.
