Consider a contrived circuit consisting of only cell and pot:
(1) a cell with constant voltage V and constant amperage A,
(2) variable resistor of resistance R initially set to its highest finite resistance and used to close the circuit with the cell.
(Assume that the variable resistor has a range of zero ohms to infinity ohms, and that its highest finite setting is guaranteed to create a closed circuit that is not a short circuit for arbitrarily large V and A, and that some resistance R greater than zero ohms is guaranteed to be a short circuit.)
Given a closed, non-open, non-short circuit comprised only of a variable resistor of resistance R, and a cell with amperage A and voltage V, what is the value of R when the circuit shorts out as we reduce R from infinity to zero?
