This generator is a necessary instrument to perform quantitative experiments on electrostatics. Its use isn’t dangerous for the operator because, even in the event of a short circuit, the maximum current reaches only 2mA because of a large output resistance. It is supplied with two highly insulating safety cables. The output voltage is adjustable continuously up to 5 kVdc. Comes with a built-in digital voltmeter with 3 digits Fixed output 6.3V/AC,3A.
