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:
Resistor Voltage (V) Current (mA)
1 3.88 43.6
2 4.48 14.45

Using this data, first find the resistance of each resistor and then calculate the following:

(a) The current that would pass through the network of resistors if they were arranged in series and connected to an 7.65 V voltage source.
Iseries =
(b) The current through the circuit if the resistors were arranged in parallel and connected to the same 7.65 V source from part (a).Iparallel =

Answer 1

Try this solution, note, the resistance of each resistor is marked with green colour, the items (a) and (b) - with red colour.
