In the network of Figure 2.59, R, = 102 and R, = 20 02. Compute the current i supplied by the 15 V source. 15 V R R R R R R R R R R R R Figure 2.59. Circuit for Problem 6 Hint: Start at the right end and by series and parallel combinations of the resistors, reduce the cir- cuit to a simple series circuit. This method is known as analysis by network reduction.
