Question

1. Consider a 4 kΩ resistor and a 25 kΩ resistor wired in series to a 3 V battery. Calculate the total current in the circuit. 2. Consider a 20 kΩ resistor wired in parallel with a 5 kΩ resistor. Calculate the equivalent resistance of the circuit. 3. Suppose you have three resistors (A, B and C) wired in parallel. The total current in the circuit is measured to be 10.0 A. If both resistors A and B have 2.0 A of current passing through each of them, how much current does the third resistor have passing through it? 4. Suppose you have 10 different resistors of different resistance values. Given the choice of pure series or pure parallel, how would you choose to wire them together if you wanted to minimize the equivalent resistance of the circuit?
