Answer:
in series combination current I is same in all three resistance but , potential difference is vary in all three resistance but total potential difference is V .
Applying ohm's law
→ V = IR. ....(1)
Now, applying ohm's law in all three resistance
→ V1 = IR1
→ V2 = IR2
→ V3 = IR3
from equation (1)
IR = V
=> IR = IR1 + IR2 + IR3
=> IR = I ( R1+R2+R3)
=> R = R1+R2+R3.
