### NCERT Solutions for Class 12 Physics Chapter 14: Points to Remember

Students can go through the important points to revise during the final examination:

• Diode: (i) By changing the external applied voltage, junction barrier of p-n junction diode can be changed.
(ii) Diodes along with the help of a capacitor or a suitable filter, can rectify AC voltage to a DC voltage.
(iii) After a certain (breakdown) voltage, the current suddenly increases in a Zener diode. This property has been used to obtain voltage regulation.
(iv) Applications of diodes: Photodiodes, Solar cells, Light emitting diode and Diode Laser, etc.
• Logic gates: (i) NAND and NOR gates are known as universal gates.
(ii) Output for OR gate will be False only when both the inputs are False.
(iii) Output for AND gate will be True only when both the inputs are True.
(iv) NAND gate is combination of AND and NOT gates.
(v) NOR gate is combination of OR and NOT gates.
• Extrinsic semiconductor: (i) Semiconductors which are doped with some impurities are known as extrinsic semiconductors.
(ii) Extrinsic semiconductors are of two types: nn-type and pp-type.
