Ebonite LOWER PRICE
A. Battery Top EHT Power Supply • Powered by a PJ996 battery
• Provides a stepped EHT output from 0-4200V (±2100V) in 700V steps via 4mm sockets
• Output current limited to 140µA • Power warning LED
Designed for safe use, this unit allows quantitative electrostatics experiments to be performed by responsible students.
Any of the stepped outputs can be connected to the top terminal via a 4mm lead, and any of the other outputs grounded so that the other six sockets are either positive or negative with respect to this. A sphere or collecting plate can be placed on the top terminal. Spooning charge is one example of an experiment that can be carried out with this unit.
