Answer:
Hope this helps!
Explanation:
"For one, the total resistance of a Parallel Circuit is NOT equal to the sum of the resistors (like in a series circuit). As you add more and more branches to the circuit the total current will increase because Ohm's Law states that the lower the resistance, the higher the current.
"
Answer:
The gain of each antenna in decibels is 353 .33 dB.
Explanation:
Given:
Frequency = 2 GHz
Diameter = 1.2 m
To Find:
The gain of each antenna in decibels = ?
Solution:
Relationship between antenna gain and effective area
-----------------------------------(1)
Where
f is frequency
is effective area
c is the speed of light
= effective area of a parabolic antenna with a face area of A is 0.56A
r is the radius
r =
r = 0.6
Substituting the values in eq(1)
=
= 353 .33 dB
Answer:
intrinsic semiconductors
Explanation:
An intrinsic semiconductor is also known as a pure conductor. In such a semiconductor there are no impurities, that is why it is said to be pure.
It has some of these properties:
1. Electrical conductivity is only based on temperature
2. The quantity of electrons is the same as the number of holes in the valence bond
3. Electrical conductivity is not on the high side
4. These materials exist in their pure forms.
