Resistors in Series and Parallel Resistor Combinations
The purpose of this lab is to verify that resistors add when in series, and combine using the "one over" or "product over sum" rule when in parallel. We will also test if currents split according to the inverse ratio of the two resistors. We will also check to see if there is a difference between VL and VTPD. 1. Set up the following circuit:

This exercise will involve the analysis of basic series-parallel DC circuits with resistors. The use of simple series-only and parallel-only sub-circuits is examined as one technique to solve for desired currents and voltages. Theory Overview. Simple series-parallel networks may be viewed as interconnected series and parallel sub-networks.

For resistors in parallel, the voltages must be the same across each resistor and the total current is the sum of the currents through each of the resistors. So, For two resistors in parallel, the above equation can be written as . Note that the rules for adding resistors in series and resistors in parallel are opposite to the rules for adding ...

Resistors in Series and Parallel. 1. Series. Students observe how the relative brightness of the LED bulb and the current through the ammeter change by placing R2 in the circuit first and then adding R3 in series according to Diagram 2 on the Instruction Sheet. Each student should record their observations on the worksheet. 2. Parallel

(a) The equivalent resistance is found by combining the 820 and 680 resistors in parallel, and then adding the 470 resistor in series with that parallel combination. (b) The current delivered by the battery is . This is the current in the 470 resistor. The voltage across that resistor can be found by Ohm’s law.

We will now investigate how resistors add in series and parallel and how these combinations of resistors behave. We will place these resistors in series and parallel circuits and measure the currents and potential differences in the circuits, comparing them to predictions based on Equations 1 thru 4.
