what is potential difference
Answers
Voltage, electric potential difference, electric pressure or electric tension is the difference in electric potential between two points. The difference in electric potential between two points in a static electric field is defined as the work needed per unit of charge to move a test charge between the two points.
SI unit: Volt
potential difference in Electrical Engineering. ... Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference or voltage across the two points. Potential difference is the work done in moving a unit of positive electric charge from one point to another.
The potential difference can be calculated using the equation: potential difference = current × resistance. This is when: potential difference (V) is measured in volts (V) current (I) is measured in amps (A).....Hope u like it
