How do you draw circuit and parellel circuit diagrams?

The placement of the symbols really determines the effective resistance of the circuit, how much power is dissipated in each resistor, how much current is running through each section of wire, etc., so there is not a specific set of rules invovled in making circuit diagrams. Often, you have to satisfy certain conditions given in the problem, and that will affect how you design the circuit. Lamps can often be regarded as resistors themselves because they also dissipate energy. Some general ideas to keep in mind when drawing circuits are differences between objects placed in series within a circuit and objects placed in parallel: When placing resistors in series, you obtain the effective resistance by adding up the individual resistances. However, in parallel, you add the inverses of all the resistances and then take the inverse of the result.
