How does stopping potential depend on the frequency and intensity of light?

Current is measured in amperes (A). A current of 4 amperes means that 4 coulombs of charge pass a point in the circuit every second. Aug 11, 2024 ... This tutorial will guide you through the process of calculating these quantities in DC circuits. 1. Current (I) Calculation: Current (I) is the rate of flow of ... The total potential difference from the surface of the earth to the top of the atmosphere is about 400,000 volts. 9–2Electric currents in the atmosphere. they find it difficult to accept the need for another measure of electricity (voltage, potential difference). ...
