>>id=example1 class=question margin=10px frame round<< The value (in pF) will be given by the first two digits (10) followed by the number of zeros indicated by the third digit (3). The value of the capacitor is thus 10,000pF or 10nF.

What are its markings likely to be? >><<
>>id=example2 class=question margin=10px frame round<< 47nF is the same as 47,000pF. Thus the marking (in pF) will show the first two digits (47) followed by the number of zeros (3). Since the tolerance is 10%, the final letter should be K. Thus the marking should be '473K'. >><<(:nl:)(:table style="clear:both":)
