Phase and Impedance Cross Scans

Impedance Current Three-Row Scan

denominator is the triangle

Impedance magnitude acts like the denominator of an AC Ohm-law current estimate: the same voltage gives less current when the impedance triangle is larger. These rows use exact magnitudes and do not track phase angle; real AC current depends on complex impedance, frequency, component tolerances, heating, and measurement uncertainty.

The same voltage gives less current as checked impedance magnitude grows. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

The small triangle gives the largest current

With impedance magnitude 5 ohms, 20 volts gives current 4 amperes.

I=205=4I={20\over 5}=4

Doubling the triangle halves the current

The same 20 volts over 10 ohms gives current 2 amperes.

The largest triangle leaves one ampere

With impedance magnitude 20 ohms, the same voltage gives current 1 ampere.
