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 4.50 22.50
2 4.50 5.00

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 8.000 V voltage source.
____

(b) The current through the circuit if the resistors were arranged in parallel and connected to the same 8.000 V source from part (a).
____

Explanation / Answer

1)r=200 ohm 2)v=900 ohm a)Rseries=1100 ohm thus i=8/1100= 7.27 mA b)R parallel= 200*900/1100=163.63 thus i= 8/163.63=48.8 mA
