Question

In this experiment you will use an online circuit board to build three circuits: a series circuit with three resistors, a parallel circuit with three resistors, and a circuit with a combination of parallel and series resistors. You will use an ammeter and a volt meter to measure the current flow and voltage across the resistors in the circuits. After you record the results of your experiment, you will be able to compare the measurements you take with what Ohm’s Law predicts. You will record the data in the Experiment Worksheet and answer questions as indicated in the experiment worksheet. Your answers should be presented in a report format.

Series Circuit Set Up

Place a battery from slide 1 in the upper middle portion of the blue work space. Place and connect a switch to the right of the battery. Place and connect an ammeter to the right of the switch (placing it in-line where we want to measure the amperage). The ammeter can be found in the second box on the right side. Moving vertically, place three (3) resistors from slide 1 in series. These will be referred to as R1, R2, and R3, respectively, from left to right. On the left side, place a wire connected to the left end of the battery and running to left and then downward, stretched to about the same height as the resistors on the right side. Place and stretch a wire running horizontally to connect the left wire and right resistors. Click on the first resistor (R1) and adjust the resistance to 4 Ω. Repeat for the other resistors. Click on the battery to ensure it is set to 10.0 V. Place a voltmeter across the first resistor and measure the voltage.

Answer 1

I have explained the Series Circuit Setup below for reference.

The circuit is built up as per the description provided above.

The description below explains the application of Ohm's Law.
