Introduction:
In this question, we are asked to determine the effect of increasing voltage across a zener diode on the temperature and vibration of crystal ions. We are given four options and we need to choose the correct one.
Explanation:
When a zener diode is operated in the reverse bias mode, it exhibits a unique characteristic called the zener breakdown. This occurs when the voltage across the zener diode reaches a certain value known as the zener voltage.
Effect of Increasing Voltage:
When the voltage across the zener diode increases, it reaches the zener voltage. At this point, the zener diode starts conducting heavily in the reverse direction, allowing a large current to flow through it. This leads to an increase in power dissipation within the diode.
Temperature:
The increase in power dissipation causes the temperature of the zener diode to rise. This is because power dissipation is directly proportional to the temperature rise according to the relationship P = I^2 * R, where P is the power, I is the current, and R is the resistance of the diode. Therefore, as the power dissipation increases, so does the temperature.
Crystal Ions:
The increase in temperature affects the crystal structure of the zener diode. The crystal ions within the diode vibrate with larger amplitudes. This is due to the increase in thermal energy provided by the elevated temperature. As the temperature increases, the crystal lattice becomes more agitated, leading to larger vibrations of the crystal ions.
Conclusion:
Based on the above explanation, we can conclude that when the voltage across the zener diode increases, the temperature increases and the crystal ions vibrate with larger amplitudes. Therefore, the correct answer is option B.
