Answer:
(A) Maximum voltage will be equal to 333.194 volt
(B) Current will be leading by an angle 54.70
Explanation:
We have given maximum current in the circuit ![i_m=385mA=385\times 10^{-3}A=0.385A](https://tex.z-dn.net/?f=i_m%3D385mA%3D385%5Ctimes%2010%5E%7B-3%7DA%3D0.385A)
Inductance of the inductor ![L=400mH=400\times 10^{-3}h=0.4H](https://tex.z-dn.net/?f=L%3D400mH%3D400%5Ctimes%2010%5E%7B-3%7Dh%3D0.4H)
Capacitance ![C=4.43\mu F=4.43\times 10^{-3}F](https://tex.z-dn.net/?f=C%3D4.43%5Cmu%20F%3D4.43%5Ctimes%2010%5E%7B-3%7DF)
Frequency is given f = 44 Hz
Resistance R = 500 ohm
Inductive reactance will be ![x_l=\omega L=2\times 3.14\times 44\times 0.4=110.528ohm](https://tex.z-dn.net/?f=x_l%3D%5Comega%20L%3D2%5Ctimes%203.14%5Ctimes%2044%5Ctimes%200.4%3D110.528ohm)
Capacitive reactance will be equal to ![X_C=\frac{1}{\omega C}=\frac{1}{2\times 3.14\times 44\times 4.43\times 10^{-6}}=816.82ohm](https://tex.z-dn.net/?f=X_C%3D%5Cfrac%7B1%7D%7B%5Comega%20C%7D%3D%5Cfrac%7B1%7D%7B2%5Ctimes%203.14%5Ctimes%2044%5Ctimes%204.43%5Ctimes%2010%5E%7B-6%7D%7D%3D816.82ohm)
Impedance of the circuit will be ![Z=\sqrt{R^2+(X_C-X_L)^2}=\sqrt{500^2+(816.92-110.52)^2}=865.44ohm](https://tex.z-dn.net/?f=Z%3D%5Csqrt%7BR%5E2%2B%28X_C-X_L%29%5E2%7D%3D%5Csqrt%7B500%5E2%2B%28816.92-110.52%29%5E2%7D%3D865.44ohm)
So maximum voltage will be ![\Delta V_{max}=0.385\times 865.44=333.194volt](https://tex.z-dn.net/?f=%5CDelta%20V_%7Bmax%7D%3D0.385%5Ctimes%20865.44%3D333.194volt)
(B) Phase difference will be given as ![\Phi =tan^{-1}\frac{X_C-X_L}{R}=\frac{816.92-110.52}{500}=54.70](https://tex.z-dn.net/?f=%5CPhi%20%3Dtan%5E%7B-1%7D%5Cfrac%7BX_C-X_L%7D%7BR%7D%3D%5Cfrac%7B816.92-110.52%7D%7B500%7D%3D54.70)
So current will be leading by an angle 54.70
Answer:
Sensor/transducer: bimetallic thermometer
Output: displacement of thermometer tip
Control Tstages: mercury contact switch (open:furnace off; closed:furnace on
Explanation:
for a standard room thermostat
: This is the device that sets/determines the temperature of an enclosure.
Sensor/transducer: bimetallic thermometer: Bimetalic thermometer are used for measuring the temperature of the ambient air
. bimetallic thermometer actually contains two metals. they undergo linear expansivity as the temperature of the room changes.in other words, they experience contraction and expansion with increase or decrease in temperature.The sensor is basically coupled with a transducer which turns the measured variable(Temperature) into something else, such as a movement on a dial or an electrical signal
Output: displacement of thermometer tip
Controller: mercury contact switch (open:furnace off; closed:furnace on)
once the contact switch is open the furnace can go off. when the contact switch is closed, the furnace will come up.
Answer:
The world's oldest dress called the Tarkhan Dress is at 5,100 to 5,500 years of age.
Does that help? Or do you need something else? I can change my answer if this is not what you need! :D

Answer:
Explanation:
They are altered by variables such as temperature hence making materials challenging when dealing with them.
