Electric Potential Difference

What is Electric Potential Difference? The unit of EPD is the Volt (V) Commonly known as voltage! Voltage is Energy

A source gives energy to electrons ▫Called an electric potential rise A load removes energy from electrons ▫Called an electric potential drop Any change in energy (rise or drop) ▫We call an electric potential difference

Voltage Video

Measuring Electric Potential Difference We use a voltmeter Always connect a voltmeter in parallel Measures the difference between energy at the two points
