Title5F20.50-1 - Series and Parallel - Meters - Resistors
Objective

Demonstrate series and parallel circuits with given resistors and the black box meters.  Quantitative values achieved. ​

StatusAvailable
Assembly Instructions

Must use a gray Tenma power supply.  Connect the first and last equipotential bar to the power supply.  Check that at least 6 black box meters have 9-V batteries in them and are working when connected to the power supply.  Plug in a demo lab-made resistor tube into each black box meter.  Provide enough short banana cables to connect the available black box meters into the circuit (2 per box).  Pull out at least 3 equipotential bars.  Discuss with instructor ahead of time to ensure all of the necessary equipment is provided.​

There is a button on the bottom right of the display screen that will toggle the meter between reading voltage and current at that point in the circuit.  You can add or remove any box assembly through the provided banana cables.  Turn off the power supply when you are finished.

Operation Instructions

​Set up the desired circuit.  Place each black box meter on the black board, connect the banana cables to the provided equipotential bars.  When ready, turn on the power supply and observe the difference in the quantitative values provided by the meters.

Analysis/Information

​A series circuit is one in which each device is connected in a manner such that there is only one pathway by which charge can traverse the external circuit.  A parallel circuit is one in which each device is placed on its own separate brach allowing multiple pathways by which charge can traverse the external circuit.

In a series circuit, the current through each of the components is the same and the voltage across the circuit is the sum of the voltages across each component.
In a parallel circuit, the voltage across each of the components is the same and the total current is the sum of the currents through each component.
