Question

What does $$50$$ UF mean on a capacitor?

Answer 1

Hint:The µF stands for microfarad. It was regular practice on older capacitors to be marked as MFD or mFd either for machinery complications to produce the µ symbol print on the covering or for other industrial reasons. But $$1$$ Farad is a big value for normal capacitors, hence we use microfarad or UF and also mention the conversion for different capacities of the capacitor.


 Complete step by step solution:
The capacitance of a capacitor can be defined as the ratio of the charge on the capacitor to the potential of the capacitor The SI unit of a capacitor is Farad. The charge that is spread on the positive plate is known as the charge on the capacitor. The potential difference between the two plates is known as the potential of a capacitor. A capacitor is a mixture of two metallic plates separated by an insulating medium where the magnitude of the positive charge spread on one plate (which is the positive plate) equals the magnitude of the negative charge on the other plate (which is the negative plate).
The S.I unit of capacitance ($$H$$) is given in coulomb/volt which is written as farad.
If $$Q=1$$coulomb and
$$V=1$$Volt,
Then$$H=1$$farad.
One farad is a very large value for normal domestic capacitors. So, domestic capacitors are marked in μF or UF (microfarad). U is a replacement for μ. $$50$$ UF means $$50$$ microfarads.

Note:The capacitance of a conductor is said to be one farad when one coulomb of charge raises its potential via one volt. This symbol F or farad is a big unit for normal scales so microfarad (mF) can be used more frequently. $$1$$ farad is the same as$$1000000$$ uF, or $$1000000$$ microfarad.
