Question

two resistor of 20 ohm and 40 ohm are connected in parallel in an electic circit. how does this current passing through the two resistors compare?

Answer 1

As they are connected in parallel the potential difference remains constant,

 R1=20 ohm and R2=40 ohm
V= I1 x R1 ----- 1
V= I2 X R2 -------2
From 1 and 2,
I1 x R1 = I2 x R2
I1 x 20 = I2 x 40
I1 / I2 = 40 / 20
I1 / I2 = 2 / 1

Therefore, I1 : I2 = 2 : 1
The current in 20 ohm resistor is double than the current in 40 ohm resistor


i hope it will help you

Answer 2

Potential difference will be constant. So,

The ratio will be 2:1
