On the corkboard at your table, you will have two conducting washers, pinned down to conducting paper the metal pushpins. One of the conducting washers is connected to a positive voltage source; the other is connected to ground. Because of this voltage difference, the two washers become charged: the one connected to the voltage source is positively charged, the one connected to ground is negatively charged. You will learn more about voltage later, but for now, we will use voltage measurements as a technique to investigate the electric field of these charged objects. If one uses a voltage probe with the two leads held a constant distance apart, one can get an idea of the direction of an electric field by finding the direction of maximum voltage difference at any given point.

Available equipment: Power supply, PASCO Voltage Probe – taped together to provide a constant distance between the leads, conducting paper, conducting pushpins, conducting washers, conducting plates, connecting wires.

Knowing how the voltage probe can be used to measure electric field direction, design an experiment to map the electric field of the two charged metal washers.

Solutions

Expert Solution

As shown in the above figure is the experimental setup. You have a fixed distance voltage measurement probe. Turn on the power supply. A charge is being generated in those conducting washers,

These charge creates a voltage field on the conducting plate.
Gradient of this field created the Electric field on this conducting plate.

Experimental steps:

You have PASCO Voltage Probe. use one terminal to +ve washer (1) first and the other terminal at point (2) , note the readings. Say V21
Next touch the terminals of PASCO probe to (2) and (3) respectively, V23. the relation is V31=V32-V21
This way find the voltage of all points on the plate as shown in the figure, with respect to the point 1.
Each dots are equally spaced. Thus one can find the electric field bu using the relation , where is the distance between two dots and is the voltage difference between those two points.
This way you know the Electric field and Voltage/Potential field on the conducting plate.
