1. exactly 90° out of phase when input frequency is f_c
2. more than 90° out of phase when input frequency is higher than f_c
3. less than 90° out of phase when input frequency is lower than f_c

Assertion (A): In some materials, ∈_r is independent of temperature while in others, ∈_r depends on temperature.

Reason (R): If permanent dipoles are absent, ∈_r varies with temperature.

1. On executing the return statement, it immediately transfers the control back to the calling program.
2. There is no restriction on the number of 'return' statements present in a function.
3. The 'return' statement must be present at the end of called function.

Assertion (A): In active region of CE output characteristics of BJT, collector current is nearly constant.

Reason (R): Base current in CE connection is very small.
