Voltage is - the force that pushes electrons through a load. Voltage drop - this value requires a certain amount of voltage to push a given current through a given amount of resistance. Series Circuit Voltage Drops - voltage will drop across each resistance that is connected to the circuit, and less voltage will be available to push the current through the next load. By the last time the current flows through the last load connected to the circuit, all voltage is used up. The sum of ...
