About this circuit
One DC source and one ideal resistor demonstrate V = I × R and P = V × I. The voltage and current probes report the positive voltage across R1 and current flowing from V1 through R1 to ground. The calculator solves any two compatible V/I/R/P values and configures V1 and R1. Maintained through Admin → Calculators.
