Question

WHAT IS THE CURRENT IF 12 OHM AND 6 OHM RESISTORS ARE CONNECTED PARALLEL AND 10 V POTENTIAL DIFFERENCE IS APPLIED?

Answer 1

Given :

▪ Two resistors of resistance 12Ω and 6Ω are connected in parallel.

▪ Pd across connection = 10V

To Find :

▪ Current flow in the circuit.

Concept :

✏ First we have to find out equivalent resistance of the parallel connection.

✏ After that, we can easily calculate current flow in the circuit with the help of ohm's law.

Calculation :

☢ Equivalent resistance :

→ 1/Rp = 1/R1 + 1/R2

→ 1/Rp = 1/12 + 1/6

→ 1/Rp = (1+2)/12

→ Rp = 12/3

→ Rp = 4Ω

☢ Current flow in the circuit :

→ V = I × Rp

→ 10 = I × 4

→ I = 10/4

→ I = 2.5A

Answer 2

Given,

• Two resistors of resistance 12Ω and 6Ω are connected in parallel.

• Pd across connection = 10V

To Find:-

⭐current flow in the circuit⭐

Formula used :-

• 1/Rp = 1/R1 + 1/R2
• V = I × Rp

Calculations:-

1/Rp = 1/R1 + 1/R2

1/Rp = 1/12 + 1/6

1/Rp = (1+2)/12

Rp = 12/3

Rp = 4Ω

Current flow in the circuit :

V = I × Rp

10 = I × 4

I = 10/4

I = 2.5A

The current flow in the circuit is 2.5A
