Question

What is the current if 12 ohm and 6ohm resistor are connected in parallel and 10v potential difference is applied?

Answer 1

Total Resistance(1/R)= 1/R1 + 1/R2

R1 = 12 Ohm

R2 = 6 Ohm

1/R = 1/R1 + 1/R2

1/R = 1/12 + 1/6 Ohm   (By Taking LCM of 12 and 6, we get 12 as LCM)

Therefore, 1/R = 1+2/12 Ohm

1/R = 3/12 Ohm

1/R = 1/4 Ohm

R = 4 Ohm

Now, Total Resistance = 4 Ohm

Potential Difference = 10 Volt

Current = ?

By Applying the above values in I = V/R, We get   (Ohm's Law)

I = 10/4 Ampere

I = 5/2 Ampere

I = 2.5 Ampere
