66.7 J of work is supplied by the refrigerator in order to remove 200J of heat from its interior. Which is having COP of 3
COP of refrigerator is defined as the ratio of heat removed from the substance (refrigerator) to Work input.
Full form of COP is Coefficient of Performance.
Formula of COP = Heat Removed(Q)/ Work input( W)
we have COP =3
Q= 200J substitute in formula
3=200/w ⇒ w=200/3 ⇒ 67J

The term "complex power" refers to the mathematical representation of electrical power. It has both real and fictitious parts, just like a complex number.
The active power is represented by the real part, while the reactive power is represented by the imaginary part. The letter S is frequently used to represent it.
What does complex power entail?The complex conjugate of the rms current phasor and the rms voltage phasor make up the complex power (in VA). As a complex quantity, its real and imaginary parts are real power P and reactive power Q, respectively.
Since the magnitude of the complex power is the apparent power, we could write it as:

V = R x I.
The variables are:
V is the voltage.R is the resistance.I is the current.At resistor R2, we have that:
The current is I1, as it is the same for the entire loop.The resistance is of 1800 ohms.The voltage is of 7.2 volts.Hence the current I1 is obtained as follows:
1800 x I1 = 7.2
I1 = 7.2/1800
I1 = 0.004A = 4mA.
Then for resistor R1, we have that:
The voltage is of 12 - 7.2 = 4.8 V, as the voltage for the entire loop is of zero.The current is of 0.004A.Hence the resistance R1 is obtained as follows:

A load of 120 + j 60 is connected to a source of 120 V with a phase angle of 30°, through a transmission line with an inductive reactance of 60 ohms. A Capacitor bank of a capacitive reactance of 60 ohms is connected in parallel to the load. Total reactive power supplied by the source to the line is:
To find the total reactive power supplied by the source to the line, we need to first calculate the total current flowing through the line.
How to use Ohm's law?We can do this by using Ohm's law to find the total resistance of the line, and then dividing the source voltage by the total resistance:
Total resistance = (120 + j60) / 120 V = 1 + j0.5 ohms
Total current = 120 V / (1 + j0.5 ohms) = 120 / (1.2 + j0.6) = 100 / 1.2 + j(-50) / 1.2 = 83.333 - 41.667j A
Next, we can use the total current and the source voltage to calculate the total reactive power supplied by the source to the line:
Total reactive power = (120 V) * (83.333 - 41.667j A) = 9960 - 5000j VAR

You need to replace a fiber optic cable that is connecting two switches together. You inspect the existing fiber cable and determine that it uses LC connectors. You also notice the cable's ferrule has a slight slant to it. Which polish grade should you use to replace the existing cable?
Angled Physical Contact polish
So, To replace the fiber optic cable that connects two switches. If it is found that the existing fiber cable to ensure it has LC connectors and also if the cable's ferrule has a slight slant to it.
Angled Physical Contact polish should be used to replace the existing cable.
What is Angled Physical Contact polish?
APC Connector is a type of fiber connector that reduces back-reflection by applying a 5° to 15° angle-polish to the end faces.
Because of the angle, the reflected light escapes into the cladding rather than remaining in the fiber core.
Angled connectors should only be mated with other angled connectors. When mated to a non-angle polished connector, insertion loss is extremely high. Angle-polished connectors typically have a higher insertion loss than good quality straight physical contact connectors.
When connected, "Ultra" quality connectors may achieve back reflection comparable to an angled connector, but an angled connection maintains low back-reflection even when the output end of the fiber is disconnected.
