Question

two resistences Xn adn 12n are connected in parallel in a circuit. if the resultant resistance in the circuit is 3n. find the value of X?
n means ohm symbol​

Answer 1

Answer:

R1 = X ohm, R2 = 12 ohm

Resultant = (R1 * R2)/ (R1 + R2)

3 = (X * 12)/ (X + 12)

3(X + 12) = 12X

3X + 36 = 12X

9X = 36

X = 4ohm
