A voltage of 47V RMS is applied across a real inductor. The current through the inductor is measured to be 29mA RMS and the phase angle between the voltage and current is measured to be 84.7. Determine the internal resistance of the inductor.

Two capacitors give an equivalent capacitance of 9.00 pF when connected in parallel and an equivalent capacitance of 2.00 pF when connected in series. a.) What is the capacitance of each capacitor? b.) John was asked to design a capacitor in which small size and large capacitance were required. He said that he can achieve that by inserting a piece of paper between the plates. Do you agree with him? Why? Is there anything else that could be done to increase the capacitance?
