Energy Transfer Apparatus

Energy Transfer Apparatus
Item# EH-0720

Product Description

The Energy Transfer Apparatus allows students to compare the electrical energy input of a small electric motor with the work done as it lifts various loads of washers. Input is measured with an ammeter, voltmeter, and watch. The amount of work performed is calculated from the mass of washers used and the distance through which they are raised.

Following the above analysis for a number of different loads of washers, the efficiency of the system can be determined and analyzed.
