How Do You Solve Parallel Circuit Equations With Two Unknown Variables?
Solving simple circuits with Kirchhoff’s Laws and Ohm’s Law can be challenging, but it’s an essential skill for anyone interested in electronics. Most introductory physics classes in electricity and magnetism teach students how to analyze simple circuits. Tests in these classes often feature problems requiring you to find unknown values in a circuit from the values you already know. Determine what kinds of components are present in the circuit. Circuit diagrams use basic symbols to represent the various types of components. A light bulb is essentially the equivalent of a resistor for the purposes of this type of problem. Although in practice the resistance of a light bulb, or other metal element, increases with increasing temperature, introductory physics classes will ask you to treat light bulbs as simple resistors. Use the arrangement of the resistors, batteries or capacitors in the circuit to determine the net resistance, capacitance or voltage. When capacitors are in parallel, the
