What Is an M4A File? A file with the M4A file extension is an MPEG-4 audio file. They’re most often found in Apple’s iTunes Store as the format of song downloads. Many M4A files are encoded with the lossy Advanced Audio Coding (AAC) codec to reduce the size of the file. Some may instead be lossless and use the Apple Lossless Audio Codec (ALAC). If you’re downloading a song through the iTunes Store that’s copy protected, it’s saved with the M4P file extension....

Power Resistor Basics The power dissipated by a resistor can be found using Joule’s first law (Power = Voltage x Current). The dissipated power is converted to heat and increases the temperature of the resistor. The temperature of a resistor keeps climbing until it reaches a point where the heat dissipated through the air, circuit board, and the surrounding environment balances the heat generated. Depending on the required wattage, a device may need a high-power resistor to prevent overheating....
