Conceptual Questions Based On Electronics Devices

Q.1. The resistance of the pn junction is low when forward biased and is high when it is reverse biased. Explain.Answer: The resistance of pn junction is low when it is forward biased because force acts on charge carriers to move them across the junction whereas the force in reverse biasing acts in opposite direction

Conceptual Questions Based On Electric Potential

Q.1. Why earth is considered to be at zero potential?Answer: Earth has very large size. Potential of earth does not change with small charge therefore it is considered as reference level and potential taken as zero. Q.2. If electric potential V within a certain region is constant, what is the nature of electric field inside

Conceptual Questions Based On Capacitance

Q.1. Where is the knowledge of dielectric strength helpful?Answer: Dielectric strength is the maximum value of electric field that can be applied across an insulatorbefore its breakdown or the magnitude of electric field intensity across insulator at which it startsconducting. This value helps us in determining the value of maximum potential, which can be appliedacross
