Resistor Schematic Diagram. I think it is easier to draw and looks better. The schematic symbol of the resistor are drawn in two different ways.
Resistor values in ohms are usually shown as an adjacent number and if several resistors are present in a circuit they will be labeled with a unique identifier number such as r 1 r 2 r 3 etc. The figure 1 above image shows how they look in reality but obviously there will be some schematic way of representing a resistor in a circuit. A low value resistor may be 10 ohms or 22 ohms.
Usually in a circuit diagram you see a component denoted by zigzag lines which look like that shown in figure 2 below image.
Even though i m from europe i like to draw the zigzag version. The figure 1 above image shows how they look in reality but obviously there will be some schematic way of representing a resistor in a circuit. A high value resistor may be 100 000 ohms 330 000 ohms 1 000 000 ohms or even higher. One common scheme is the rkm code following iec 60062 it avoids using a decimal separator and replaces the decimal separator with a letter loosely associated with si prefixes corresponding with the part s resistance.
