In this type of circuit, the total current is equal to the sum of the currents throught each resistor. This is because the electrons are able to flow through a new path created by each resistor, in other words, there are two or more different paths. This is proven by the equation IT=I1+I2+I3.In addition, the voltage drop across each branch is equal to the voltage of the source. VT=V1=V2=V3 shows this concept.
Here is an example of a complex circuit.
In this type of circuit, finding the current involves the equation I = V/RE. First, find the equivalent resistance of the different parts of the circuit need to be found. Then the sum of those resistances will be the equivalent resistance of the entire circuit.To find the voltage drop of each resistor, it is necessary to use the equation V=RI, but you need to plug in that specific resistor's resistance and total current. Also, sometimes you can use V2=V3=VT-V1. This is used to find the voltage across each resistor in a parallel circuit.
I hoped that this posting has helped you to gain a complete understanding of the fun filled circuit world!
