In this section we will tackle about the series parallel circuit. This topic is also discussed by our teacher when we take up Physics 2. So we in circuits 1 this topic is really applied especially when we find the voltage,current, and resistance.
SERIES CIRCUIT
A series circuit in which the resistor is connected or short, so the current has only one path. The current flowing through the resistors. The total resistance of the circuit is found by adding up the resistance value of the resistor.
R=R1+R2+R3+.....
In this example the circuit is a closed path, so the current will flow in counter clockwise, and according to the series resistance, we should total or add the resistances in the circuit
Req=R1+R2+R3
Parallel Circuits:
A parallel circuit is a circuit in which the resistors are arranged with their heads connected together, and their tails connected together. The current in a parallel circuit breaks up, with some flowing along each parallel branch and re-combining when the branches meet again. The voltage across each resistor in parallel is the same.
The total resistance of a set of resistors in parallel is found by adding up the reciprocals of the resistance values, and then taking the reciprocal of the total:
equivalent resistance of resistors in parallel:
1 / R = 1 / R1 + 1 / R2 + 1 / R3 +...
Example:
1/Req=R1//R2//R3
=1/10+1/2+1/1
=625ohms
Resistors are said to be connected in Series, when they are daisy chained together in a single line. Since all the current flowing through the first resistor has no other way to go it must also pass through the second resistor and the third and so on. Then, resistors in series have a Common Current flowing through them as the current that flows through one resistor must also flow through the others as it can only take one path.
