Statement: 10 mA current enters the node formed by two parallel resistors having their resistances 20 Ω and 2 Ω. Find the divided current by applying the current divider rule.

Solution: We know the general formula for any divider circuit is:

And in case of two resistors:

The equivalent resistance is:

R

R

R

In our case for two resistors:

The current across first resistor: I

and across the second resistor: I

You can also verify the results from current divider rule calculator.
Solution: We know the general formula for any divider circuit is:

And in case of two resistors:

In our present case, I

_{t}is 10 mA. Whereas the R_{t}can be calculated by the formula:The equivalent resistance is:

R

_{t}=
R

_{1}* R_{2}/ R_{1}+ R_{2}R

_{t}= =
2 * 20

2 + 20

R

_{t}= 1.81 ΩIn our case for two resistors:

The current across first resistor: I
