R.2.53 An applied voltage VT across a series connection consisting of two resistors R 1 and
R 2 divides the voltage VT into two voltage drops V 1 and V 2 as indicated in Fig ure 2.6.
Each voltage is a function of R 1 , R 2 , and VT referred to as the voltage divider rule given
by the following relation:
