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
Impedance current scan rowThe checked hypotenuse is the current denominator.RXZ

Doubling the triangle halves the current

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

I=2010=2I={20\over 10}=2
Impedance current scan rowCurrent follows the full impedance magnitude.RXZ

The largest triangle leaves one ampere

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

I=2020=1I={20\over 20}=1
