WHAT TO NOTICE

Voltage drives, resistance limits

A complete circuit lets charge flow. Components in series share the same current; parallel branches share the same voltage. Kirchhoff’s laws keep charge and energy balanced at every junction and around every loop.

V = IRP = VIΣI_in = ΣI_out

Educational circuit solver. Presets support DC, RC, RL and basic AC demonstrations; unsupported custom networks are identified rather than treated as engineering-grade SPICE models.
