scientific 2 012-04346B Equipment Setup Figure 1 e. A plastic template is included with the PASCO scientific Field Mapper, for drawing circles. (seeFigure 3) Place the template on the conductivepaper and draw the circles with the conductive inkpen. (If desired, you may first draw the circletemplate ...

scientific 3 012-04346B 4. Connect the electrodes to a battery, DC power supply,or any other potential source in the 5 to 20 VDC rangeusing the supplied connecting wires. (see Figure 4) Thepotential source should be capable of supplying 25 mA.(If possible, the potential should be equal to the fullsc...

scientific 4 012-04346B arrow. Repeat the action of pivoting and touching withthe front lead until the potential reading in a givendirection is highest. Draw a new arrow. Repeat theaction of putting the ground lead at the tip (head) ofeach new arrow and finding the direction in which thepotential di...

scientific 5 012-04346B Experiments The following are only some suggested experiments inmapping equipotentials and field gradients using the PASCOField Mapper. The true value of the equipment, lies in itscomplete flexibility permitting the user to design any systemof charged bodies and then to map t...

scientific 6 012-04346B Dipoles of Like Charge + Questions How does the field of this configuration compare withdipoles of opposite charge? (See experiment “Dipoles ofOpposite Charge”.) What distortion of the field is produced by the large elec-trode around the perimeter of the paper? Dipoles of Opp...

scientific 7 012-04346B Floating Electrode + Before drawing the circular electrode, map the equipotentialsof the two straight electrodes. Draw the circular electrodeand again map the equipotentials. Questions How does the circular electrode distort the field? What is the potential of the circular el...

scientific 8 012-04346B Line and Circular Source a b c + Draw only the line and point source “a.” Map theequipotentials. Add circular electrode “b” and again map theequipotentials. Add circular electrode “c” and again map theequipotentials. Questions How is the spacing of equipotentials affected by ...

scientific 9 012-04346B Triode Equipment needed but not supplied: 5K Potentiometer a a 5K Potentiometer + Use a 5 K potentiometer to provide three potentials. Con-nect the three short electrodes with wires “a.” Do not letthese wires touch the black paper except at the conductiveink electrodes. Quest...
