in the circuit diagram even in suppose the resistor R1 R2 and R3 have the value of 5 ohm 10 ohm 30 ohm respectively which have been connected to a battery of 12 volt calculate the current through the each resistor be the total current in the circuit and see the total circuit resistance

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

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

➝ 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.

the answer is a 3.8cm
