A thermistor is used for
Answer: Option
Explanation:
The resistance of a thermistor decreases with increases in temperature. It is used to monitor hot spot temperature of electric machines.
12.
In a series RLC circuit excited by e = Em sin ωt is seen that LC < 1/ω2. Then
Answer: Option
Explanation:
At frequencies less than resonant frequency current leads voltage.
13.
A resistance R is connected to a voltage source Vs having internal resistance Rs. A voltmeter of resistance Rm is used to measure the voltage across R. The voltmeter will read
Answer: Option
Explanation:
Effective resistance of R and Rm is 
The reading is 
.
14.
When a lead acid battery is being charged, the specific gravity of the electrolyte
Answer: Option
Explanation:
Specific gravity of electrolyte is highest when battery is fully charged and is lowest when discharged.
15.
Assertion (A): The response of a network to unit impulse can be obtained directly from the network function.
Reason (R): The response of a network for any input can be obtained from impulse response.
Answer: Option
Explanation:
Convolution integral can be used to find the response for any arbitrary input in terms of impulse response.
