In question number 3, which of the two receivers picks up the larger signal when D is turned off?

Answer»

`R_(1)`
`R_(2)`
`R_(1)` and `R_(2)`
None of these.

Solution :If D is SWITCHED off.
`R_(1)` picks up `y=a" COS"wt`
` :. LT I_(R_(1))GT =(1)/(2)a^(2)`
`R_(2)` picks up `y=3a" cos"wt`
` :. lt I_(R_(2))gt =(9)/(2)a^(2)`
Thus `R_(2)` picks up larger signal compared to `R_(1)`.
