Question

are distance of 12 ohm is connected in parallel without another resistance X result and resistance of the combined is 4.8 on what is the resistance of x​

Answer 1

Answer:

This is simple. When two resistors R1 and R2s are in parallel, the equivalent resistor is

R = R1 * R2 /(R1 + R2)

Given R1 = 12 ; R = 4.8

Therefore 4.8 = 12 * R2 /(12+R2)

4.8(12 + R2 ) = 12R2

57.6 + 4.8R2 = 12R2

57.6 = 12R2–4.8R2 = 7.2R2

Therefore R2 = 57.6/7.2 = 8 Ohms

X = 8 Ohms
