Three resistors R1, R2, and R3 are connected in series with R1 < R2 < R3. Choose all correct answers below. The total resistance of the combination is (a) less than R1, (b) less than R3, (c) greater than R3, (d) greater than 3R3, (e) equal to R1 + R2 + R3. Two resistors R1 and R2 are connected in parallel with R1 < R2. Choose all correct answers below. The total resistance of the combination is (a) less than R1, (b) less than R2, (c) greater than R2, (d) greater than 2R2, (e) equal to (R1 * R2) / (R1 + R2). A wire of length L1 and diameter d1 has resistance R1. A second wire of the same material has length L2 = 2L1 and diameter d2 = 2d1. The resistance of wire two is R2. Choose the correct value for R2: (a) R2 = R1, (b) R2 = 2R1, (c) R2 = 4R1. 4. If a circuit element carries a current of 3.71 A, and the voltage drop across the element is 8.69 V, what is the resistance of the circuit element? Show your work.

You make a parallel combination of resistors consisting of resistor A having a very large resistance and resistor B having a very small resistance. The equivalent resistance for this combination will be: a) slightly greater than the resistance of the resistor A. b) slightly less than the resistance of the resistor $\mathrm{A}$. c) slightly greater than the resistance of the resistor B. d) slightly less than the resistance of the resistor B.
Resistors R1 > R2 > R3 are connected in parallel in a circuit. A. The largest current passes through R1. B. Resistor R3 dissipates the most power. C. The same current passes through all the resistors. D. Resistor R1 dissipates the most power. E. All the resistors dissipate equal amounts of power.
