Answer #1

Why does a dry tree oimb or a broken conductor lying on dry or frozen ground not always trip out the circuit protection?

Ans: A dry tree branch or a dry ground has a very high resistance and as ice is a poor conductor of current so dry frozen ground also offers a very high resistance.

So if any open (broken) current carrying conductor touches to those surfaces, there will be very less amount of fault current flowing to the ground due to high resistance so that sometimes the fault current is not sufficient to trigger the protection circuit to trip out.

What physical process is launched with the switching on of the toaster? Why does the current decrease from its initial value and reach another steady value? Choose the best answer from below. A. When switched on, heating element of the toaster acts as a parallel connection of a resistor and an inductor. This connection reacts to any change of the current with a delay. As the result, current initially increases to a greater value and then reaches the saturated value....
