Circuit Solution Tips & Tricks• Stay symbolic as long as possible
Define new equivalent variables as necessary• Order of analysis
Series/parallel equivalentsSource transformationsKVL/KCL equations (if you see a path forward)Node Voltage / Mesh Current Analysis (otherwise)
Example ProblemFind vL(t) for vs(t) = 170cos(2 60t) and for Rs = 10 , N = 0.1, and RL = 50
Resonance ExampleFind vo(t) for vin(t) = 10sin( t) and = 2 100 kHz, R = 10 , L = 10 H, and C = 253 nF
Phasor SuperpositionFind vo(t) for vin(t) = 10sin( t) + 10sin(2 t) + 10sin(0.5 t) and = 2 100 kHz, R = 10 , L = 10 H, and C = 253 nF
