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

Answer»

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

Solution :If B 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=a" cos"wt`
` :. lt I_(R_(2))gt =(1)/(2)a^(2)`
THUS `R_(1)` and `R_(2)` pick up the same signal.
