The Iraq War: How We Spent $800 Billion (and Counting) Follow @sarah_childressMarch 18, 2013, 1:36 pm ET. The Iraq war cost twice as much as the war in Afghanistan, and more than 16 times as much as the Bush administration predicted.
emitter. 1  a person or thing that emits. 2  Electronics. an electrode on a transistor from which a flow of electrons or holes enters the region between the electrodes.
Common Emitter Configuration. Here the emitter terminal is common to both the input and output signal. The arrangement is the same for a PNP transistor. Used in this way the transistor has the advantages of a medium input impedance, medium output impedance, high voltage gain and high current gain.
