2.) A Zener diode is a semiconductor device made of silicon that allows current to flow in both directions.
<h3>What is a semiconductor?</h3>
A semiconductor is a device whose conductivity lies between the conductivity of the conductors and the insulators.
Due to the inclusion of an impurity or temperature effects, a solid substance with conductivity between that of an insulator and that of most metals. Semiconductor devices, particularly silicon devices, are key components of most electronic circuits.
Zener diode:-
A Zener diode is a semiconductor device made of silicon that allows current to flow in both directions.

The switch has been in position a for a long time. At t = 0, the switch moves from position a to position b. The switch is a make-before-break type so there is no interruption of the inductor current. a. Find the expression for i(t) for t ≥ 0. b. What is the initial voltage across the inductor after the switch has been moved to position b? c. Does this initial voltage make sense in terms of circuit behavior? d. How many milliseconds after the switch has been put in position b does the inductor voltage equal 24V? e. Plot both i(t) and v(t) versus t

Answer: True
Explanation: The amount of natural gas supplied in the residential area has lesser cost as compared with the electric power industry. The cost is lesser for the natural gas because it is abundantly available resource in the environment and electricity is generated by several methods and thus supplied so there is more effort and resources required and this costs more .Therefore, natural gas is cheaper as compared with electric power .
Answer: Equilibrium temperature they reach is 383 K
Explanation:
As we know that,
.................(1)
where,
q = heat absorbed or released
= mass of gold = 1.3 kg
= mass of copper = 2.1 kg
= final temperature = ?
= temperature of gold= 300 K
= temperature of copper = 400 K
= specific heat of gold =
= specific heat of copper =
Now put all the given values in equation (1), we get
Thus equilibrium temperature they reach is 383 K
