In this lab, you will investigate the relationships among voltage, current, and resistance in series and parallel circuits.

Procedure

Part 1: Series Circuit with Two Resistors, Designed in Terms of Resistance

1. Design a circuit that has two resistors connected in series. Given that you have a 20 V battery, choose resistors that will produce a current of 0.2 A. Record the resistance in data table 1.

Using the flash animation available on the launch page of the lab activity, construct a series circuit according to the specifications. Represent your circuit on graph paper, labeling each element in the circuit. Calculate the current through and voltage drop across each resistor, and record in data table 1.

2. Using the ammeter and voltmeter, determine the current through and voltage drop across each resistor by touching leads to the wires before and after each individual resistor. Record the values in data table 1
