Question

You have two resistors of resistances 30 ohm and 60 ohm. what resistances can you get by combining the two

Answer 1

in series we get equivalent resistance equals 90 ohm. in parallel equivalent resistance is 20 ohm.

Answer 2

Answer:20 ohms

Explanation:The formula to find the combined resistance of a resistor in a parallel circuit you use this formula:

(R1*R2÷R1+R2)

Where R1 is the first resistor and R2 is the second resistor.

So when you substitute the values u get:

(30*60÷30+60)=20 ohms
