1.3.1 Analogue Circuit Theory
1.3.1.1 Resistors
Resistors are the simplest linear components encountered when applying circuit theory techniques. The symbol for a resistor is shown in Figure 1.3.1(a). If an emf V (measured in Volts) is applied across the terminals of the resistor (resistance R, measured in ohms), it can be shown, as in (b), that the current flowing through the resistor is linearly proportional to the current I (measured in amperes).
Figure 1.3.1 Resistor and voltage/current characteristic.
This relationship is better known as Ohm’s law, i.e.:
