In a series LCR circuit, the total voltage across the circuit is given by the phasor sum of the voltages across the individual components (resistor, inductor, and capacitor). This is due to the phase differences between the voltages across the inductor and capacitor.

1) The voltage of the source will not necessarily be leading the current in the circuit. The phase relationship between the voltage and the current in an LCR circuit depends on the relative values of the resistance, inductance, and capacitance. If the inductive reactance is greater than the capacitive reactance, the voltage will lead the current. If the capacitive reactance is greater than the inductive reactance, the voltage will lag the current.

2) The voltage drop across each element can be less than, equal to, or greater than the applied voltage, depending on the phase relationships. In this case, the voltage drops across the resistor, inductor, and capacitor are 8V, 6V, and 12V respectively, which are all less than the total voltage (which is the square root of the sum of the squares of the individual voltages, or sqrt(8^2 + 6^2 + 12^2) = 16V).

3) The power factor of the circuit is given by the cosine of the phase angle, which is the resistance divided by the impedance. The impedance is the square root of the sum of the squares of the resistance and the net reactance (which is the difference between the inductive and capacitive reactances). Without knowing the values of the resistance, inductance, and capacitance, we cannot determine the power factor.

4) Based on the above, the correct answer is "None of these".
