If wired correctly, this will not damage the fan or the USB port, as the fan will take less current at a lower voltage.
The main problem with this arrangement is the fan would either not start, or would run very slowly, so probably useless for cooling anything.
If you can get a 5V fan, not more than 500mA, this would be much more effective.
(Note- If wired incorrectly, reverse polarity could damage both USB port and fan, short circuit could damage your USB port.)

When might you omit a break statement from the end of a case in a switchstatement?
You can omit the break statement at the end of a case whenever you want execution to flow into the next case, or when the case is the last case. For instance, if you wanted to test a character regardless of whether it was upper or lower case, you might use the following: void f(char c) { switch (c) { case 'a': // execution flows into next case... case 'A': // do something break; case 'b': // execution flows into next case... case 'B': // do something else } }
Write a java program using switch case to find zodiac signs?
Let's say you want a method which will determine if the given character is a vowel, consonant, or other (non-letter). // Will return a String representation of what the given character is: // "vowel" "consonant" or "other" public static final String getTypeOfChar(final char c) { // since chars are an integer data type in Java, we can switch on them switch(c) { case 'a': // all of these cases "fall through" to the next non-case statement case 'e': // if any of them matches case 'i': case 'o': case 'u': return "vowel"; case 'b': // again, all of these cases fall through case 'c': case 'd': case 'f': case 'g': case 'h': case 'j': case 'k': case 'l': case 'm': case 'n': case 'p': case 'q': case 'r': case 's': case 't': case 'v': case 'w': case 'x': case 'y': case 'z': return "consonant"; default: // if we have no matches yet, do this return "other"; } }
Write program to convert a string in lower case without using library function?
It is not certain if the question asked to convert lower case to upper case, or upper case to lower case. This answer assumes the latter. You could easily change this around for the former. ConvertToLower (char*psz) { while (*psz != '\0') { switch (*psz) { case 'A': *psz = 'a'; break; case 'B': *psz = 'b'; break; case 'C': *psz = 'c'; break; case 'D': *psz = 'd'; break; case 'E': *psz = 'e'; break; case 'F': *psz = 'f'; break; case 'G': *psz = 'g'; break; case 'H': *psz = 'h'; break; case 'I': *psz = 'i'; break; case 'J': *psz = 'j'; break; case 'K': *psz = 'k'; break; case 'L': *psz = 'l'; break; case 'M': *psz = 'm'; break; case 'N': *psz = 'n'; break; case 'O': *psz = 'o'; break; case 'P': *psz = 'p'; break; case 'Q': *psz = 'q'; break; case 'R': *psz = 'r'; break; case 'S': *psz = 's'; break; case 'T': *psz = 't'; break; case 'U': *psz = 'u'; break; case 'V': *psz = 'v'; break; case 'W': *psz = 'w'; break; case 'X': *psz = 'x'; break; case 'Y': *psz = 'y'; break; case 'Z': *psz = 'z'; break; } psz++; } Warning. Do not be tempted to replace the switch statement with ... if (*psz >= 'A' && *psz <= 'Z') *psz += 32; ... because that will only work on ASCII implementations, and it is most definitely not portable, such as in EBCDIC implementations.
What does CASE stands for related to agriculture?
It doesn't stand for anything. Case is not an acronym, it is just a company name for a farm machinery dealership just like that of John Deere, New Holland, Massey Ferguson, etc. However, the name Case IH stands for Case International Harvesters. The name "Case" comes from the man who founded the Case company, Jerome Increase Case. Case became Case IH when International Harvester company merged with Case a number of years later.Another vague possibility is the Clean Air, Sustainable Environment initiative.

Can you use a 9v dc 200mA ac adaptor in place of a 500mA?
Yes. The current rating should be the same or greater than the original. This means the adapter can supply up to 500mA; In your case it only needs to supply 200mA, so it is more than up to the job.
