Question

You are given two resistors, an ammeter, a voltmeter, and a voltage source. By connecting each resistor singly to the voltage source and taking voltage difference and current measurements on the single resistor, you find the following data for each resistor: Using this data, first find the resistance of each resistor and then calculate the following: The current that would pass through the network of resistors if they were arranged in series and connected to an 7.19 V voltage source. The current through the circuit if the resistors were arranged in parallel and connected to the same 7.19 V source from part (a).

Explanation / Answer

First resistance = V/I = 65 ohm Second resistance = 420 ohm Therefore In Series Net resistance = 420 + 65 = 485 ohm Therefore Current = V/Req = 0.01482 A In Parallel Resistance = (65*420)/485 = 56.3 ohm Current = 0.1277 A
