AT 121 Chapter 6 Lab 2 Using a DVOM What m k and M mean Name Date The metric system a means of standardization is based on the number 10 Numbers with 12 or more zeros in them can be cumbersome and both space and time consuming Therefore a system of prefixes makes calculations easier These prefixes together with their associated symbols and values are TERM SYMBOL milli kilo mega m K M VALUE 1 1 000 0 001 1 000 1 000 000 Notice that prefixes for numbers greater than one are symbolized by capital letters but symbols for prefixes of less than one are lower case letters As shown in the chart above to convert any value to mega move the decimal point six places to the right to convert any value to kilo move the decimal point three places to the right to convert any value to milli move the decimal point three places to the left The following list provides some examples of how prefixes would be used in conjunction with common circuit variables The abbreviation provided with each example is the way that value would actually be written on schematics or other technical information 1mV 001V 1mA 001A 50mV 050V 500mV 5V 1 450 mV 1 450V 1K 1000 Funny how a car that sells for 1K 1000 1 2K 1 200 345K 345 1M 1 000 000 1 2M 1 200 000 7M 7 000 000 234M 234 000 Convert the values to electrical units 1 2 3 4 5 6 7 8 9 10 788 A equals how many milliamperes 788mA 0 0788 A equals how many milliamperes 78 8mA 50 mA equals how many amperes 050A 110 mA equals how many amperes 110A 7 A equals how many mA 7 000mA 30 mA equals how many A 030A 55 mA equals how many amperes 00055A 235 000 000 milliamperes equals many A 235 000A 12 V equals how many mV 12 000mV 243 mV equals how many volts 0 243V 1 11 12 13 14 10 V equals how many millivolts 10 000mV 3V equals how many kV 003kV 3mV equal how many volts 003V 300 milivolts equal how many kilovolts 0003kV 15 16 17 18 19 20 21 32 k equals how many 32 000ohms 32M equals how many ohms 32 000 000ohms 3500 ohms equals how many k 3 5kOhms 3 5 k equals how
