10.3: Resistors in Series and Parallel
If several resistors are connected together and connected to a battery, the current supplied by the battery depends on the equivalent resistance of the circuit. The equivalent resistance of a combination of resistors depends on both their individual values and how they are connected. The simplest combinations of resistors are series and parallel connections (Figure …

current
Current is the amount of electrons flowing due to the electric field that the voltage causes. So, while the speed of electrons is pretty slow, the speed at which a change in electrical field propagates is very high – in fact, it''s the speed of light. You can imagine the piece of metal as a resistor.
