First Electric Machine BuiltOFrancis Hauksbee

OAround 1700

OSingle-barrelled pump

OUsed static electricity:

No wires.

Created when the glass globe became charged.

Parts

The most important

parts are:

O Pulley

O Glass globe

Where did the electrical energy

consumed come from?

The machine became charged by:

● Rotating fastly a pulley

● Rubbing the glass globe with the hands

● Friction and mechanical energy transformations

● Device used for making experiments in a vacuum
