Electric field plotting lab report

No work is being done in this area, but if you move off those lines, then work will be done as either negative or positive. Because the electric field has both a magnitude and a direction, it is known as a vector field.

You will plot equipotential lines lines of equal electric potential and sketch in lines representing the electric field between the electrodes. Nonetheless, the results will be meaningful in the large region between the poles, so reconnect the circuit as before, and begin collecting data: Just as a ball can have different amounts of mass depending on the type of ball baseball, basketball, etc…a test charge can have different amounts of charge depending on the source.

Indicate with arrows how the electric field begins on areas with positive charge and ends on areas with negative charge. I like the part about the potential energy along the equipotential lines. For the electric dipole configuration, are any of the equipotential lines straight?

For your lab report, you should consider the differences between these lines and those of the parallel plate charge distribution. Finally, draw in the electric field lines corresponding to these 7 equipotential lines, produced by the electric dipole source charge configuration.

One was the interference of the metal in the table. Find and plot the equipotential lines for the electric dipole configuration using the same method as was used for the parallel plate configuration. Record the voltage from the voltmeter next to that point on your paper copy of the set up. Turn on the voltmeter, and set it to the 20 V scale.

Thus, we can express the electric field produced by a single point charge as: On the other hand, for an object with charge in an electric field, the direction of the force depends on whether the charge is negative or positive. Outside of the region between the two plates, you should find that the equipotential lines are no longer parallel; rather, they bend in a particular way.

If the electric potential changes significantly over a small distance as in the region near the point source in the image abovethe electric field is strong; if the electric potential changes only by a small amount over a large distance as in the region far away from the point source in the image abovethe electric field is weak.

One was how the galvanometer was read. For our experiment we used a power supply to provide a constant voltage between to conductors, this was connected to a plate which contained a chain of resistors.

This would imply that either the electric field points in two directions, or the electric potential has two values, at a single point in space!

Charges And Fields

Move the handheld probe down to the grid point at Row 8, Column 8, and repeat the measurement, again recording the value on your photocopy. Why do they look different? Indicate with arrows how the electric field begins on areas with positive charge and ends on areas with negative charge.

Therefore, electric field lines radiate away from positive charges and terminate at negative charges. Next, find the voltage value at each of the center points between the poles along the grid.

Be sure to distinguish your electric field lines from your equipotential lines using a legend, and place arrows on the electric field lines to indicate their direction. For our lab, we experiment with three different kinds of these boards, each having a different configuration of electrodes.

Plotting equipotentials and electric field lines To prepare the setup for data collection and plotting of the equipotential lines, do the following: Figure 1 shows what the electrode plates look like which were attached to the board.

After all the null points were found a curved was drawn between them. The relationship between the electric field and the electric potential is clear when considering a single dimension.

This happens because the ball is in a gravitational field and the gravitational field produced by the Earth interacts with the mass of the ball.

Place the stationary probe on a center point, and find other locations yielding a 0 V potential difference with the center point, mark these locations on the photocopy, and connect them.Lab Report 2: Electric Field Plotting Abstract The purpose for this experiment was to use charged electrodes on a flat sheet of conducting paper to discover an electric field.

On the construction paper there were several locations identified and connected that the equipotential lines ran perpendicular to the electric field%(20).
