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.
Collector-emitter: The main current that flows through the transistor. Voltage placed across the collector and emitter is often referred to as V ce, and current flowing through the collector-emitter path is called I ce. Base-emitter: The current path that controls the flow of current through the collector-emitter path.n a PNP transistor, the emitter is the positive side of the transistor. The collector and base are the negative sides. Most circuits that you can build with an NPN transistor can also be built with a PNP transistor. But if you do, you must remember to flip the power connections.
