Two Resistor Series Circuit. In a series circuit the output current of the first resistor flows into the input of the second resistor. We connect the end of the first resistor to the head of the second resistor and so on.
Series resistors connection has the same value of current. The total resistance in the circuit is equal to the sum of the individual resistances since the current has to pass through each resistor in sequence through the circuit. If two resistors or impedances in series are unequal and of different values then the total or equivalent resistance rt is equal to the mathematical sum of the two resistances.
In a parallel circuit all of the resistor leads on one side of the resistors are connected together and all the leads on the other side are connected together.
The total resistance in the circuit is equal to the sum of the individual resistances since the current has to pass through each resistor in sequence through the circuit. Three resistors connected in series to a battery left and the equivalent single or series resistance right. Therefore the current is the same in each resistor. We connect the end of the first resistor to the head of the second resistor and so on.
