Question

hello!!

How can we easily turn mixed combination of resistors in to simpler combination of resistors ( series or parallel combination of resistors)?

need a appropriate and easy answer !!

answer it step by steps!!!

hope I will get a great answer!!!

thank you!!!

Simpler Combination of resistor:-

Resistors can be connected both in series, parallel or a combination of both. In series circuit electrons travel only in one path. Here the current will be the same which passes through each resistor. The voltage across resistor in a series connection will be different.

Combination of Resistors

Resistors can be combined in two ways; series and parallel. Combination of more than one resistor is called equivalent resistor. We first look at the resistors in series;

Resistors in Series

a. In this types of circuit, amount of currents passing through the resistors are equal and this current comes from the battery.

i=i1=i2=i3

b. Sum of the potential differences of each resistor is equal to total potential difference of the circuit or potential difference between the ends of battery.

V=V1+V2+V3

c. If ,

V1=i1.R1

V2=i2.R2

V3=i3.R3

V=V1+V2+V3

i.Req=i1.R1=i2.R2=i3.R3

Since the currents are equal to each other.

Req=R1+R2+R3

When you add new resistors to the circuit in series, equivalent resistance of the circuit increases.
