Archetype Sub-90 Dry-Wipe Invariant (Series-Parallel Resistor Networks, Potential Dividers & Variable Sensor Meter Tables): Use the product-over-sum shortcut Rₚ = (R1*R2)/(R1+R2) (and R/n for n identical parallel resistors). In meter trend tables, take the extreme limit R(var) -> infinity (open circuit) to read ammeter/voltmeter changes in 5 seconds.
