7.
in a series sinusoidally driven lcr ac circuit, the
current lags the applied emf. the rate at which
energy is dissipated in the resistor, can be
increased by
(1) decreasing the capacitance and making no
other change
(2) increasing the capacitance and making no
other change
(3) increasing the inductance and making no other
change
(4) increasing the driving frequency and making no
other change
