2. Sometimes light fixtures are controlled by more than one switch. Circuits need to be designed so that flipping one of the switches turns the light on when it is off, and turns the light off when it is on. Design logical circuit that accomplishes this when there are two switches. Explain, how and why will your circuit work.
