Name the device 'D' which is used as a voltage regulator in the given circuit . Rewrite the circuit by replacing 'D' with the proper circuit symbol. Give its working principle. |
Answer» SOLUTION :D is a zenar diode ![]() PRINCIPLE : If you INCREASE or decrease the INPUT VOLTAGE it results in the increase or decrease in voltage drop across `R_1` but the voltage across the zenar diode remains constant. `therefore` A constant voltage acts across `R_2`. |
