Question

Hi there,

I am having troubles with the following questions, any help would be much appreciated!

We have a series RLC circuit with an AC voltage source: The resistance is 100Ohm, the inductance is 10mH, the capacitance is 10mF. Select all the right answers.

At 10Hz What is true?

Question 13 options:

	The current is lagging behind the voltage at the source
	The voltage is lagging behind the current at the source
	The current and voltages are in phase at the source
	The voltage across the resistor is larger than the voltage across the inductor
	The voltage across the inductor is larger than the voltage across the capacitor
	The current through the inductor is larger than through the resistor

We have a series RLC circuit with an AC voltage source: The resistance is 100Ohm, the inductance is 10mH, the capacitance is 10mF. Select all the right answers.

At 60Hz

Question 14 options:

	The absolute phase difference between the current and the voltage at the source is less than 6 degrees
	The absolute phase difference between the current and the voltage at the source is less than 3 degrees
	The absolute phase difference between the current and the voltage at the source is less than 2 degrees
	The absolute phase difference between the current and the voltage at the source is less than 5 degrees
	The absolute phase difference between the current and the voltage at the source is less than 1 degree
	The absolute phase difference between the current and the voltage at the source is less than 4 degree

We have a series RLC circuit with an AC voltage source: The resistance is 100Ohm, the inductance is 10mH, the capacitance is 10mF. Select all the right answers.

I have an Irms of 1A through the circuit what is true?

Question 15 options:

	At 0Hz the power is almost the same as the power of a DC circuit with only a 100 Ohm resistor and a 1A current
	The power in a DC circuit with only a 100 Ohm resistor and a 1A current is almost the same as the average power of our RLC circuit at 60 Hz.
	At 60Hz the average power is smaller than at 10Hz
	At 60Hz the average power is the same as at 10Hz
