A simple parallel electrical circuit diagram with a 12V battery, switches, light bulbs, and a dimmer.

Draw the Battery: Draw two parallel lines, one longer (positive terminal) and one shorter (negative terminal), labeled “12V Battery”. Draw the Parallel Branches: From the positive terminal, draw a horizontal line that splits into five branches (using junctions). Each branch represents one light circuit. For Each Wall Light Branch (4 branches): Draw a switch symbol (a break in the line with a diagonal line crossing it). After the switch, draw a lamp symbol (a circle with a cross inside). Connect the other end of the lamp back to the negative terminal line. For the Ceiling Light Branch: Draw a switch symbol. After the switch, draw a dimmer symbol (a resistor symbol with an arrow diagonally across it). Then draw the lamp symbol. Connect back to the negative line. Complete the Circuit: Connect all branches from the positive line back to the negative terminal line, completing the parallel circuit. Mehr sehen
