Resistors and resistive circuits

Values of resistance are given in ohms (Ω) or multiples of ohms. In circuit diagrams, they are coded R for ohms, k for kilohms (thousands of ohms) and M for megohms, or millions of ohms. The letters R, k or M are placed in the position of the decimal point when a resistance value is written against the resistor symbol, as explained in Chapter 1.
