Why do they look different? Electric dipole charge configuration: Plotting equipotentials and electric field lines When you are finished with the above measurements, switch the conductive sheets so that the electric dipole configuration's conductive sheet is on top, clipped to the platform as before.

Once all the points were found then the power supply was located to another conductor and the same process was preformed. Place it to the side on your lab table, and record any measured values directly onto the appropriate location on the sheet.

Why do they look different? Because the electric field has both a magnitude and a direction, it is known as a vector field. The closer together the electric field lines come together, the stronger the electric field is. Be sure to discuss in your lab report why these electrodes are equipotentials! Also, the electric field lines perpendicularly intersect the equipotential lines, and cannot ever cross one another! This also means you are staying at zero potential energy, with no work being done. This value should be approximately equal to your set voltage source; if it is slightly less, then your connect may be bad, so adjust the setup to ensure maximal connection between conductive surfaces! Electric dipole charge configuration: Plotting equipotentials and electric field lines When you are finished with the above measurements, switch the conductive sheets so that the electric dipole configuration's conductive sheet is on top, clipped to the platform as before.

With these equipotentials plotted, you will then draw in the electric field lines for each configuration based on your expectations. The gel used in my experiment will be made from agarose.

This region should be near the middle of the area between the two parallel plates, away from the edges. In this laboratory experiment, we will explore these concepts by plotting the equipotential lines in the space between two different charged electrodes one positive and one negative.

When beginning or terminating an electric field line at a source charge, be sure that it is perpendicular to the electrode's surface because electrodes are equipotentials too. With the stationary probe still placed on the bottom plate, touch the handheld probe to the center dot in Row 9, Column 8.

In other words, the electric field is the surrounding charges which create an electric field around a given point. There are a few components that compose a gel electrophoresis chamber.

Next, find the voltage value at each of the center points between the poles along the grid. Parallel-plate charge configuration: Plotting equipotentials and electric field lines To prepare the setup for data collection and plotting of the equipotential lines, do the following: Slide the parallel-plate configuration sheet onto the platform with the other conductive sheet beneath it for improved conductivity , and connect the metal clips on the platform to the metal strips leading to the electrode at each end. In your procedures, you say that the null lines are black and the equipotential lines are colored. Nonetheless, the results will be meaningful in the large region between the poles, so reconnect the circuit as before, and begin collecting data: With the dipole sheet positioned on top of the parallel plates sheet on the platform, you will repeat the same procedure as above for the previous configuration. This will supply equal and opposite charges to the electrodes, and maintain a constant electric potential difference between them. Record and label the voltages of each plate onto the photocopy sheet, using the reading on the voltmeter and setting the low-voltage electrode at 0 V. This means the DMM voltmeter is configured to measure voltage up to 20V. For the electric dipole configuration, where is the electric field strength greatest? The key to this lab is the evaporation rate is directly related to the energy of the light shining on the drop. Then, connect the power supply to the point charges. Metal plates are conductive, so that the charge within them is evenly spread out, and there is no difference in charge or voltage between any two points along the plate! Be careful: Unlike the parallel plate configuration, the electric dipole does not produce mostly uniform straight field lines. First, determine the voltage between the two poles by placing the stationary probe at the low-voltage pole, and placing the handheld probe at the other high-voltage pole. Finally, draw in the electric field lines corresponding to these 7 equipotential lines, produced by the electric dipole source charge configuration.

Because the electric field has both a magnitude and a direction, it is known as a vector field.
