True/False. Enter T or F for statement. (Do not enter the words “true” or “false”. Just the capital letter T or F) (1 point each) In electrical engineering, we may encounter quantities over very broad ranges, for examples, 1 terabyte (TB) is 1012 bytes, 1 exajoule (EJ) is equal to 1018 joules, 1 picowatt (pW) is 10-12 watt, and 1 femtoampere (fA) means 10-15 ampere. If two identical resistors are connected in series or in parallel, they will both have the same current density. With a rise in temperature, the resistance of a metal will generally decrease, whereas the resistance of a semiconductor will increase. Faraday’s Law is useful for calculating the voltage induced in a coil by a time-varying magnetic field. A time-varying current through a wire creates a static magnetic field. Currently, most of the electricity in the US is produced from coal. Gauss’ Law for Magnetics implies that there are magnetic monopoles (point sources of magnetic field). For a given electrical load, the rms power is one-half of the real power. Transformers are essential for achieving high efficiency in electrical power transmission in large scale power systems. Magnetic cores can be used to reduce inductance.
