ELECTRICITYNote: Some power supplies operate on 120 volts 60 Hz ac but others operate on 230 volts 50 Hz ac.Which voltage your power supply uses depends on which country you are in.For more information see the answers to the Related Questions shown below.
A personal computer's power supply receives 120 volts of AC and converts it to 3.3, 5, 12 volts of DC power.Another answerThe secondary voltage could be any number of voltages depending on what the power supply was designed for. Your best bet is to get a DC voltmeter and measure the output voltage of each wire on the output side.
12v 1000mA means that the maximum output of that unit is 1000 milliamps at 12 volts. 12v 150 mA means that the maximum output of that unit is 150 milliamps at 12 volts. So if you need 150 milliamps at 12v either will do. BUT if you need over 150 milliamps at 12v then you must go for the 1000 mA unit. By the way there are 1000 milliamps in 1 amp.
It means there are problems because one machine or program doesn't work well with another one. In Australia, a wall socket has 240 volts; US televisions need 120 volts. How's that for a "compatibility issue"? Consider means you have to think about it, otherwise your TV is junk.
Watts = current x volts, so you have to multiply Kw value by 1000 to get watts, then divide by the applied voltage. examples. 2Kw kettle (U.S) current = 2 x1000 divided by 120, or 16.7 amps 2Kw kettle (UK) current = 2 x1000 divided by 240 or 8.35 amps 100 watt car amplifier current = 100 divided by 12 volts = 8.5amps
150 volts is 125% of 120 volts.
50% of 120 volts = 50% * 120 = 0.5 * 120 = 60 volts
120% of 80 = 96 80% of 120 = 96 70% of 150 = 105 150% of 200 = 300 200% of 150 = 300
120 as a percentage of 150 is 80%
15% of 120 is equal to 12% of 150. 15% of 120 = 18 12% of 150 = 18
120% of 150 = 120% * 150 = 1.2 * 150 = 180
18000
150%
150% of 80 is 120.
125% of 120= 125% * 120= 1.25 * 120= 150
80% of 150 = 80% * 150 = 0.8 * 150 = 120
25 percent increase.
