Question

Rv=1/c+r solve for c
I know the answer I'm confused as to how to get there

Answer 1

rv=1/2

Explanation:

Answer 2

See below

Explanation:

Given

• rv=1/c+r

Solving for c

• Its not clear what the denominator is: c or c+r so doing both

Denominator is c:

• rv = 1/c + r
• 1/c = rv - r
• c = 1/(rv - r)

Denominator is c + r:

• rv = 1/(c + r)
• rv(c + r) = 1
• rvc + r²v = 1
• rvc = 1 - r²v
• c = (1 - r²v)/rv

or more simplified

• c = 1/rv - r

Note. If you know the answer it should help how to get it
