14 Chapter 2: Basic Circuit Elements CHAPTER 2: PROBLEMS 2.1 Sketch the current vs. voltage relationship for an ideal current source, an ideal voltage source, and an ideal resistor. 2.2 In the circuit shown below determine the power dissipated by the voltage source. 2.3 Find the power dissipated in the current source below. + - 5 V 2 mA 6 k + - 16V 4k 4mA
15 Analog Electronics 2.4 Find the current, Iz, through resitor Rz below. Also, find the power dissipated in all of the circuit elements (Ix, Vy, and Rz). 2.5 The battery on a camcorder is rated as a 6V battery with a capacity of 1 Amp-Hour. (a) How many coulombs of charge are stored in this battery when it is fully charged? (b) How many Joules (Watt-seconds) of energy are stored in this battery when it is fully charged? (c) If the camcorder draws 500mA of current from the battery, how much power does it dissipate? (d) If the camcorder draws 500mA of current from the battery, how long will the camcorder run (assuming it runs continu- ously) starting with a fully charged battery, before the bat- tery is exhausted? 2.6 A manufacturer of AA rechargeable 1.5 V batteries claims that their batteries can deliver 5 mA for 20 hours.
