## PHYS345 Electricity and Electronics

**Hint for 6.7**
Take the output as the voltage across the parallel *RC* circuit.

The ratio of output to input voltage will be

*V*_{o} / *V*_{s} = (1 - w^{2}/32 + *j*w/8)^{-1}.

Find the resonant frequency by finding the frequency at which the magnitude of the function above is a maximum.
*It is not possible to zero out the reactance by changing the frequency.*
You may ignore the question about bandwidth...
