Question

How much current flows in the circuit if two resistors of 6 connected in parallel are

supplied with potential difference of 12 volts?​

Answer 1

4 A

Step-by-step explanation:

Firstly we need to calculate the equivalent resistance. Since, two resistors of 6 connected in parallel, so equivalent resistance will be given by,

`\longrightarrow` 1/R = 1/R1 + 1/R2

`\longrightarrow` 1/R = (1/6 + 1/6) Ω

`\longrightarrow` 1/R = (1 + 1)/6 Ω

`\longrightarrow` 1/R = 2/6 Ω

`\longrightarrow` R = 6/2 Ω

`\longrightarrow` R = 3 Ω

We know that,

`\longrightarrow` V = IR

• V denotes p.d (12V)
• I denotes current
• R denotes resistance (3 Ω)

`\longrightarrow` 12 = I × 3

`\longrightarrow` 12 ÷ 3 = I

`\longrightarrow` 4 Ampere = I
