Answer the following statement(s) true (T) or false (F)
1. The unijunction transistor is made by combining four layers of semiconductor material.
2. The UJT has three paths through it for current flow.
3. By varying the resistance connected in series with the capacitor, the amount of time needed for charging the capacitor can be changed, thereby controlling the pulse rate of the UJT.
4. The pulse rate is determined by the amount of resistance and capacitance connected to the emitter of the UJT.
5. The programmable unijunction transistor can be used to phase shift an SCR.
