Answer:0.853
Explanation:
Given
Reliability of A is 0.90
Reliability of B is 0.80
Reliability of C is 0.99
B has a backup with reliability of 0.8
i.e. B has a component in parallel to it.
A,B& C is series.
B actual reliability is

Answer:
a)The electric Field will be zero at the point between the sheets
b)
c)
Explanation:
Let be the surface charge density of the of the non conducting parallel sheet.Let consider a Gaussian surface in the form of of cylinder such that its cross-sectional is A . Then there will be flux only due to cross sectional area as the curved sectional is perpendicular to the the electric field so the Electric Flux due to it is zero.
Now using Gauss law we have, E be the electric Field at the distance r from the sheet then
The Field will be away from the sheet and perpendicular to it.
a) The Electric Field between them
b)The Electric Field to the right of the sheets
c)The Electric Field to the left of the sheets
Answer:
The reflected resistance in the primary winding is 6250 Ω
Explanation:
Given;
number of turns in the primary winding, = 50 turns
number of turns in the secondary winding, = 10 turns
the secondary load resistance, = 250 Ω
Determine the turns ratio;
Now, determine the reflected resistance in the primary winding;
Therefore, the reflected resistance in the primary winding is 6250 Ω
