Consider the circuit shown in the figure. Suppose the four resistors in this circuit have the values (in ohms) R1 = 12 Ω, R2 =6.8 Ω, R3 = 6.6 Ω, and R4 = 15 Ω, and that the emf of the battery is e= 18 V.
A. Find the current through each resistor using the rules for parallel resistors.
B. Find the current through each resistor using Kirchoff'srules.
