Answer: d) Inductors
Explanation: Inductors are the electric component commonly known by the name of coils as well. The work done by inductors is when the electric current flows through the coils of the wire then there is production of the magnetic field. They are the component that have the inductance in particular amount according to the circuit.So, coils of various dimensions are designed to introduce specified amount of inductance into a circuit are called inductors.
Answer:
evaluative criteria.
Explanation:
Evaluative criteria is a term in marketing that Is used when a customer decides to go for a different kind of product that is different from the one they originally had in mind because of certain attributes. These attributes could be objective in nature such as power and fuel economy or it could subjective when things like prestige and convenience are being looked at.
<u>Explanation:</u>
1) When we invest in stock it means we are investing in long term investment. It includes risk factor also.
2) We can make money from stocks by retaining them for a long period and selling them when their price rises.
3) dividends are paid out of distributable profits. Some companies provide dividends regularly which act as a regular source of income for investors.
4) Capital gain is the benefit obtained on selling a capital asset and if we face loss on selling the capital asset it results in capital loss. Capital assets are like stock, bonds, properties, etc.
Answer:
critical clearing angle = 70.3°
Explanation:
Generator operating at = 50 Hz
power delivered = 1 pu
power transferable when there is a fault = 0.5 pu
power transferable before there is a fault = 2.0 pu
power transferable after fault clearance = 1.5 pu
using equal area criterion to determine the critical clearing angle
Attached is the power angle curve diagram and the remaining part of the solution.
The power angle curve is given as
= Pmax sinβ
therefore : 2sinβo = Pm
2sinβo = 1
sinβo = 0.5 pu
βo =
⁰
also ; 1.5sinβ1 = 1
sinβ1 = 1/1.5
β1 =
= 41.81⁰
∴ βmax = 180 - 41.81 = 138.19⁰
attached is the remaining solution
The critical clearing angle =
≈ 70.3⁰
Assuming V1 is the anode and v2 the cathode (Anode is P region and Cathode is N)
Answer:
a) Reverse bias
b) Forward bias
c) Forward bias
Explanation:
Forward bias: It happens whenever the N region of the diode is more positive than the P region. Hence, the depletion zone increase ceasing the current through the circuit -> V1 -V2 < 0
Reverse bias: It happens whenever the P region of the diode is more positive than the N region. In this case, the depletion zone begins to shrink, if enough voltage is applied current could go through the circuit -> V1 - V2 > 0
a) V = V1 - V2 = 0 - 2 = -2 -> -2 is smaller than zero therefore, we have reverse bias
b) V = V1 - V2 = 4.5 - 2.8 = 1.7 -> 1.7 is greater than zero therefore, we have forward bias
c9 V = V1 - V2 = -1 - -1.3 = 0.3 -> 0.3 is greater than zero therefore, we have forward bias
