Volt and Amp are two types of units of measurement that you are most likely to come across when learning some topics in physics. The two units of measurement are dependent on each other, especially when you consider their relationship using ohm's law. From the equation of this law, you can easily get the value of one of the values of the other two parameters are given.
First, the major difference between volt and the amp is that volt is the basic unit of measurement that is used in measuring the quantity of voltage being supplied, which amp or ampere is the basic unit of measurement of current, i.e., the rate of flow of electric charge.
While it is not possible to determine the amount of current that is flowing at a particular time with our eyes, the number of volts being supplied by most power sources are usually specified. For example, most batteries are produced with a specified voltage, while this is not the same with current.
