72. The rather simple circuit shown below is known as a voltage divider. The symbol consisting of three horizontal lines is represents "ground" and can be defined as the point where the potential is zero. The voltage divider is widely used in circuits and a single voltage source can be used to provide reduced voltage to a load resistor as shown in the second part of the figure. (a) What is the output voltage Vout of circuit (a) in terms of R1, R2, and Vin ? (b) What is the output voltage Vout of circuit (b) in terms of R1, R2, RL, and Vin? Vin R1 Vin R1 Vour Vout R2 R2 RL O V (a) (b)
