The voltage applied to a circuit is $$100\sqrt2\cos\left(100\mathrm{πt}\right)$$ volts and the circuit draws a current of $$10\sqrt2\;\sin\left(100\mathrm{πt}+\mathrm\pi/4\right)$$ amperes. Taking the voltage as the reference phasor, the phasor representation of the current in amperes is
A
$$10\sqrt2\;\angle-\mathrm\pi/4$$
B
$$10\;\angle-\mathrm\pi/4$$
C
$$10\;\angle+\mathrm\pi/4$$
D
$$10\sqrt2\;\angle+\mathrm\pi/4$$

In a series $$RLC$$ circuit at resonance, the magnitude of the voltage developed across the capacitor
A
is always zero
B
can never be greater than the input voltage
C
can be greater than the input voltage, however, it is $${90^ \circ }$$ out of phase with the input voltage
D
can be greater than the input voltage, and is in phase with the input voltage.
