Two problems with this electric analogy are a) Voltage and current are related by I=V/R (which I guess you could also express as (let ((I (/ V R))) I)) and b)

Two problems with this electric analogy are a) Voltage and current are related by I=V/R (which I guess you could also express as (let ((I (/ V R))) I)) and b) Brevity and clarity are closer to the ideas of resistance and/or impedance. The shorter and more precise the language, the less it prevents the problem from being solved.
