Problem P. 4683. (December 2014)

P. 4683. There are a lot of alike \(\displaystyle 100~\Omega\) resistance resistors in the lab. Two of them are connected in series to a 120 V voltage supply. How many resistors are to be connected in parallel to one of the resistors, in order that the power dissipated at the other reaches the value of 100 W?
