Answer:
Answer: Two resistors of resistance R1 and R2 are connected in series. ... The two resistors joined in series is replaced by an equivalent single resistor of resistance R such that the potential difference V across it, and the current I through the circuit remains same.

Answer:
R net= R1+R2+.......+Rn
step by step
Explanation:
when in series the charge or current (i) flowing is same but the potential difference (V) is different
So,
Vnet=V1+V2+..... +Vn
now according to ohm's law V=iR
iRnet= iR1+iR2+...+iRn
take i common on both sides
we get
R net= R1+R2+.......+Rn
