Question

Consider the circuit shown in the figure. (a) Let the equivalent resistance of the circuit when the switch is open be Req, open and the equivalent resistance when the switch is closed be Req, closed. Find the difference (in ?) between the two equivalent resistances, Req, open - Req, closed. Req, open - Req, closed = ? (b) When the switch S is closed, the equivalent resistance drops to 60.0% of the original value. Determine the value of R (in ?). ? (c) What If? What would the voltage (in V) between points a and b have to be for 180 W to be delivered to the circuit when the switch is closed? Assume that R has the value found in part (b). V
