series and paralel circuits

Ohm's law states that current in a resistance varies in direct proportion to voltage applied and inversely proportional to resistance.It is the relationship between voltage, current, and resistance. (V=IR) When more then one resistor is connected to a circuit they can be in either series or parallel patterns. A series circuit is one that the components are connected end to end so that current has only one path to follow through the circuit. …

…o make sure that the switch is in proper working order. If we were to do the whole experiment again just to see if the results would be different because of a faulty switch, we could set up the circuit exactly as stated in the lab manual only this time without a switch in place. This would allow full connection throughout the circuit without having to worry about a faulty switch.
