Given :
Three identical resistors of resistances 5Ω, 10Ω and 30Ω are connected with a battery of 12V

To Find :
We have to find current through the each resistor and equivalent resistance of circuit

SoluTion :
➝ Equivalent resistance of series connection is given by
➝ We know that, Equal current flow through each resistor in series connection.
➝ As per ohm's law, Current flow through a conductor is directly proportional to the applied potential difference.
◈ Equivalent resistance :
⇒ Req = R1 + R2 + R3
⇒ Req = 5 + 10 + 30
⇒ Req = 45Ω
◈ Current flow in circuit :
⇒ V = IReq
⇒ 12 = I × 45
⇒ I = 0.27A
፨ Therefore, 0.27A current will flow through each resistor.
