Lecture 2 figures 2 Fig. 2-6: The symbol for a resistor. Fig. 2-7: A graphical representation, or I-V plot, of Ohm’s Law, I = V/R . Fig. 2-8: Representation of a voltage source. A battery is one type of voltage source, which has a special symbol but which we will model in our circuits in the same way as any other voltage source. Fig. 2-9: Representation of a Current Source. Fig. 2-10: Circuit consisting of a Voltage Source and a Resistor.

Fig. 2-14: Symbols for a Dependent Voltage Source (left) and a Dependent Current Source (right). Lecture 2 figures 4 Ex: Using energy conservation and Ohm’s Law, find I in the circuit shown in Fig. 2-15. Fig. 2-16: A voltage source (battery) driving the current I through a series combination of two resistors. Fig. 2-17: A voltage source (battery) driving the current I through a parallel combination of two resistors. Ex: Using energy conservation and Ohm’s Law, find I s in the circuit shown in Fig. 2-16. Fig. 2-15: A resistor, with the current i(t) and the potential difference v(t) labeled consistent with the passive sign convention ....
