Explanation:
I think I will say it is because most, if not all resistors have been made to standard already.
The value for the resistor that is chosen for two fixed arms from the Wheatstone Bridge have to be quite bear each other, as much as possible. The arm that moves and the other that doesn't move, their resistance values are made to be quite close as well. This makes the resistance of the arm that moves to be set somewhere in the middle, and as a result, the measurements don't exceed beyond the resistance range of the arm that moves.
I hope you understand?
Answer:
Explanation:
The deatailed diagram of VCRS is given below such
1-2=Isentropic compression in which temperature increases at constant entropy
2-3=Isobaric heat rejection i.e. heat rejected at constant pressure(condensation)
3-4=Irreversible expansion or throttling in which enthalpy remains constant
4-1=Isobaric heat addition(Evaporation)
Answer:
R min = 28.173 ohm
R max = 1.55 × ohm
Explanation:
given data
capacitor = 0.227 μF
charged to 5.03 V
potential difference across the plates = 0.833 V
handled effectively = 11.5 μs to 6.33 ms
solution
we know that resistance range of the resistor is express as
V(t) = ...........1
so R will be
R = ....................2
put here value
so for t min 11.5 μs
R =
R min = 28.173 ohm
and
for t max 6.33 ms
R max =
R max = 1.55 × ohm
Answer:
The resistance of a coil of aluminum wire at 18°C is 200 Ω. The temperature of the wire is increased, and the resistance rises to 240 Ω. If the temperature coefficient of resistance of aluminum is 0.0039/°C at 18°C, determine the temperature to which the coil has risen.
Explanation:
Given :
The resistance of a coil of aluminum wire at 18°C is 200 Ω.
The temperature of the wire is increased, and the resistance rises to 240 Ω.
The temperature coefficient of resistance of aluminum is 0.0039/°C at 18°C
To find :
the temperature to which the coil has risen
Solution :
Let the temperature to which the coil has risen be 't₂'
t₁ = 18°C
R₁ = 200 Ω
R₂ = 240 Ω
α = 0.0039/°C
