1. Consider connecting three resistors of resistances 39 Ω, 54 Ω, and 720 Ω together.
a) What is the largest resistance you can obtain in Ω? (b) What is the smallest resistance you can obtain in Ω?
2. Consider the circuit in the following diagram, where the resistances are R1 = 0.15R, R2 = 2R, R3 = 0.55R, and R4 = 6R, where R = 41 Ω. The circuit is connected to a V = 4.9 V source.
a) Input an expression for the equivalent resistance of the circuit in terms of R1, R2, R3, and R4.
b) Input an expression using the Req and V for power expended by the circuit.
c) What is the power P, in watts?
