Current is the rate at which charge is flowing. Resistance is a materialâs tendency to resist the flow of charge (current). So, when we talk about these values, weâre really describing the movement of charge, and thus, the behavior of electrons.
Direct current is the type of current that comes from a solar cell or battery. The positive and negative terminals of these power sources never change, so the current runs in the same direction the entire time. Direct current does not allow for power to be efficiently transported over large distances.
