Electrostatics Voltage Source - ES-9077



This compact unit is ideal for performing experiments in electrostatics. It may be used as a source of charge or to maintain an object at a constant potential. Since the current required for such applications is small (on the order of nanoamps), high megohm resistors (120 MΩ per kV) are placed in series with each output.

Output voltages ( 1000, 2000 and 3000 VDC ) allow students to investigate how voltage affects charge density on spheres, capacitor plates, etc. A 30 VDC source is also provided for experiments with capacitors.
