The circuit in Figure P5.56 is used as a variable delay in a burglar alarm. The alarm is a siren with an internal resistance of 1 k?. The alarm will not sound until the current i0 exceeds 100?A. Use a graphical or numerical solution to find the range of the variable resistor R for which the delay is between 1 and 2 s. Assume the capacitor is initially uncharged.
