Question

what do you mean by series combination

Answer 1

Heya......!!!!

_____________________________

Series Combination means the Resistors are connected in series . *( See the pic in the attachment )*

Equivalent resistance in Series combination .

Consider 3 resistors , R1 , R2 and R3 connected in series .

By Ohm' Law the potential drop across each resistor is given by :-

=> V1 = IR1
=> V2 = IR2
=> V3 = IR3

Let total potential be ( V )

V = V1 + V2 + V3

V = IRe ( Re is the equivalent resistance . )

Thus ,,

•• IRe = IR1 + IR2 + IR3

♦ Re = R1 + R2 + R3 .

we can say that equivalent resistance in series combination is the individual sum of resistance .


In Series Combination :-»»


=> The current through each resistor is same .

=> The equivalent resistance is greater than that of individual resistance in series combination .

=> the Total voltage drop is equal to the sum of the voltage across each resistor .
