Question

Derive an expression for equivalent resistance in series

Answer 1

Answer:

Derive an expression for the equivalent resistance of three resistances connected in series. Series combination: If a number of resistors are joined together so that the current flowing across each resistor is the same, then the resistances are said to be connected in series.

Answer 2

Explanation:

V=I*R

V1=I*R(1)

V2=I*R(2)

V3=I*R(3)

V=V1+V2+V3

I*R=I*R(1)+I*R(2)+I*R(3)

I(R)=I(R1+R2+R3)

CURRENT (I) WILL GET CANCELLED FROM BOTH SIDES

R=R1+R2+R3
