A diode AM detector with the output circuit consisting of `R=1k Omega and C=1 mu F` would be more suitable for detecting a carrier signal of

A

0.1kHz

B

0.5kHz

C

1kHz

D

10kHz

Text Solution

Verified by Experts

The correct Answer is:
D
Given R=`1 k Omega`
or `R=1 times 10^3`
`C=1mu F`
or `C=1 times 10^-6 F`
In this condition frequency of carrier signal
`1/(RC) gt gt f_C`
`1/(1 times 10^3 times 10^-6) gt gt f_C`
`therefore f_c gt gt 1kHz`
Because frequency is greater than 1.
So, `f_c=10kHz`

A series LCR circuit with R= 20 Omega , L=1.5 H and C= 35 muF is connected to a variable frequency 200 V ac supply. When the frequency of the supply equals the natural frequency of the circuit, what Is the average power transferred to the circuit in one complete cycle?

For one-electron species, the wave number of radiation emitted during the transition of electron from a higher energy state (n_(2)) to a lower energy state (n_(1)) is given by: bar v =(1)/(lamda)=R_(H) xx Z^() ((1)/(n_(1)^(2)) (1)/(n_(2)^(2))) where R_(H)=(2 pi m_(s) k^(2) c^(4))/(h^(3) c) is Rydberg constant for hydrogen atom. Now, considering nuclear motion, the accurate measurement would be obtained by replacing mass of electron (m_(e)) by the reduced mass (mu) in the above expression, defined as mu =(m_(n)xx m_(e))/(m_(n) +m_(e)) where m_(n) = mass of nucleus. For Lyman series, n_(t) =1 (fixed for all the lines) while n_(2) = 2, 3, 4 .... For Balmer series: n_(1) = 2 (fixed for all the lines) while n_(2) = 3,4,5 .... If proton in hydrogen nucleus is replaced by a positron having the same mass as that of an electron but same charge as that of proton, then considering the nuclear motion, the wavenumber of the lowest energy transition of He+ ion in Lyman series will be equal to
