FAQ

What is the Voltage?
Voltage is the difference in electric potential between two points, which is defined as the work needed per unit of charge to move a test charge between the two points. Voltage is usually measured using the Volt for Electric Potential. Note that the value of Voltage is always negative.
Can the Voltage be negative?
Yes, the Voltage, measured in Electric Potential can be negative.
What unit is used to measure Voltage?
Voltage is usually measured using the Volt[V] for Electric Potential. Millivolt[V], Microvolt[V], Nanovolt[V] are the few other units in which Voltage can be measured.
