resistors

Hi. Can someone please walk me through how to do the following problem? "Two resistors are connected in series to a battery with an emf of 12 V. The voltage across the first resistor is 2.2 V and the current through the second resistor is 0.15 A. Find the resistance of teh two resistors." Thank you.

Resistors Networks

"Three resistors (R, 1/2R, 2R) are connected to a battery. (a) If the resistors are connected in series, which one has the greatest rate of energy dissipation? (b) Repeat part (a), this time assuming that the resistors are connected in parallel."

inductor/capacitor

Hi. Can someone please help me with this conceptual question? "An inductor and a capacitor are to be connected to a generator. Will the generator supply more current at a low frequency if the inductor and capacitor are connected in series or in parallel?" Thank you.

AC vs. DC

Hi. Can someone please help me with this conceptual question? "In considering an ac circuit consisting of a light bulb in series with an inductor, we know that the effect of the inductor is to cause the light bulb to shine less brightly. Would the same be true in a direct-current (dc) circuit? Explain." Thank you.

LC circuit, phase angle

Hi. Can someone please help me with this conceptual question? "An LC circuit is driven at a frequency higher than its resonance frequency. What can be said about the phase angle for this circuit?" Thank you.
