\n" ); document.write( "To solve this problem, one needs to assume the applied voltage is constant, or the voltage drop across the resistance to be measured is constant while the resistance varies. Because a LINEAR circuit would not behave this way, you should NOTE that this implies the circuit is non-linear (contains digitial logic, diodes, transistors, or other nonlinear components):
