# Electric field plotting lab report

While you do this remember to leave the standing voltage probe on point 8,9. Connect the RED positive terminal of the voltmeter to the handheld probe, and the BLACK negative terminal to the stationary probe with the attached base.

Finally, draw electric field lines from this configuration by drawing several lines which are always perpendicular to both the equipotential lines and to the surface of any conductors.

You will plot equipotential lines lines of equal electric potential and sketch in lines representing the electric field between the electrodes. These lines are electric field lines for the parallel plate charge distribution.

When you are finished you should have 7 equipotential lines between the two parallel plates. Now, you want to find points that have no potential difference when compared to point 8,9.

Orient your carbon sheet on the platform as you did for the parallel plates. Record this on your Workheet and also label the electrodes on your sketch with these values. Record the voltmeter value for this point on your photocopy. Once you have drawn the equipotential lines on your photocopy, you should be able to sketch the electric field lines.

Put the standing voltage probe onto point 8,9. Repeat this for a few different points until you have enough to determine the shape of the line. Unlike the parallel plate configuration, the electric dipole does not produce mostly uniform straight field lines.

In a way, the map of these equipotential lines can be thought of as a contour map similar to those of geographical elevation maps, in which points along the same elevation line are at the same vertical elevation.

The sheet with the plates is oriented such that the row numbers increase with increasing voltage, from low to high. Since we know opposites attract, a positive test charge will move toward the negative side of the electric field.

Figure 2 Why do this in your classroom? 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.

The calibration of the galvanometer would be a systematic error, not a random one another random would be for example the pencil marks of the points. The two common source charge configurations we will examine are the parallel plate configuration as present in parallel plate capacitors and the dipole configuration as present in electric dipoles.

Label the low and high voltage plates on your copy including the voltages on them, i. For the electric dipole configuration, where is the electric field strength greatest?

Continue this process until you have recorded the voltage of every center point between the parallel plates. With the stationary probe still placed on the bottom plate, touch the handheld probe to the center dot in Row 9, Column 8. One was the interference of the metal in the table.Electric field maps can be produced by mapping an electric fieldâ€™s equipotential lines, and then connecting them with electric field lines.

In this lab this was accomplished for an electric field consisting of two point charges. Determine the variables that affect the strength and direction of the electric field for a static arrangement of charges.

Investigate the variables that affect the strength of the electrostatic potential (voltage).

Explain equipotential lines and compare them to the electric field lines. For an.

PHY Lab 1 - Electric Field Plotting The purpose of this lab is to develop the concept of electric field $(\vec{E})$ and electric potential $(V)$ by investigating the space between a pair of electrodes connected to a source of direct current (DC) electricity.

(a) Copy the above figure and sketch eight electric field lines on it (equally spaced around the inner conductor). (b) What, approximately, is the magnitude of the electric field at r = 1 cm, 2 cm, and 3 cm, where r is measured from the center of the inner conductor?

You should express the.

Purpose: The purpose of this lab was to get an introduction to mapping electric ultimedescente.com electric field is identified by a capital E and at a certain point it equals the force on a test charge divided by the amount of the charge (E=F/g).

Lab Report 2: Electric Field Plotting PHY ABSTRACT: The purpose of this experiment was to find and understand electric field and equipotential lines, and the relationship between them in two different conductive fields.

These fields were presented as parallel lines as an equivalent to parallel plate capacitor and two concentric circles as an equivalent to coaxial cylinders%(7).
