Assertion: Discharging graphs of two C.R. circuits having the same value of C is shown in figure. From the graph we can say that `tau_(C_1)gttau_(C_2)`

Reason: `R_1gtR_2`

A

If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

B

If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

C

If Assertion is true, but the Reason is false.

D

If Assertion is false but the Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
A, B

In graph 1 , discharging is slow.
Hence `tau_(C_1)gttau_(C_2)`
Further,
`tau_C=CR`
`tau_CpropR (as C=constant)`
