Unit hAs hectoampere-second Electric Charge In the field of electric charge, a unit known as the hectoampere-second (hAs) is used to represent a quantity of charge. This unit is a combination of two basic units: ampere-second (As) and the prefix 'hecto' (meaning 100 times). An ampere-second (As) is a unit of electric charge where one ampere represents the flow of one coulomb of charge per second. Hence, one ampere-second equates to one coulomb of charge (1 As = 1 C). In other words, an ampere is the measure of the rate of flow of electric charge, while an ampere-second quantifies the total amount of charge that has passed through a point in a specific time period. Now, when we add the prefix 'hecto' to ampere-second, it multiplies the unit by 100. So, one hectoampere-second (hAs) is equal to 100 ampere-seconds or 100 coulombs of charge (1 hAs = 100 As = 100 C). This means that a charge of 1 hectoampere-second corresponds to 100 coulombs of charge passing through a point within 1 second. To sum up, a hectoampere-second (hAs) is a unit of electric charge used to express the quantity of charge in terms of the rate of flow of charge (in amperes) multiplied by the time (in seconds) and scaled by a factor of 100.
