Question

How much resistance must be connected in parallel with a 360-Ω resistor to obtain an equivalent resistance Req of 120Ω?

Answer 1

Answer:

hi

Explanation:

Answer 2

Answer:

180

Explanation:

1/R(eq) = 1/R1+ 1/R2

total resistance= 120ohm

therefore

1/120= 1/360+ 1/R2

1/R2= 1/120-1/360

therefore

1/R2= 3-1/360

1R2= 1/180

therefore

R2= 180 ohm
