1.A representation of an actual electric circuit or
electronic device by a simple circuit whose behavior is very
near to that of the actual circuit over a specified range of
conditions is called as equivalent circuit.
2.The use of equivalent circuits is in analysis and design
operations associated with electronic circuits as it is
mainly composed of linear, passive elements.
3.Two of the best-known equivalent circuits are the Thévenin
equivalent circuit and the Norton equivalent circuit.

As a water tank loses heat, the temperature drops by 2 K/min when a heater is on, the system gains temperature at 4 K/min. A two-position controller has a 0.5 min control lag and a neutral zone of ± 4% of the setpoint about a setpoint of 323 K. Plot the heater temperature versus time. Find the oscillation period
