Homework Statement
The actual value of the capacitor Rahal will receive may be different from the value the
catalogue states. The manufacturer guarantees that the maximum percentage difference
below/above the catalogue value will be –10% / +50%. Rahal orders one of the 400 V 1000 µF capacitors. Within what range will its actual value lie?
Homework Equations
Q=CV
therefore C is inversely proportional to V
The Attempt at a Solution
I would say:
1100µF = max
500µF = min
BUT THE ANSWER IS
900µF = min
1500µF = max
WHY?
thanks
