Question

In order for charged parallel plates to act as a capacitor, which of the following must be true? "

	a.	The plates must be connected to a voltage source.
	b.	The material between the plates must not conduct electricity.
	c.	The plates must be connected to ground.
	d.	There must be zero potential difference between the plates.

Electric current will flow only:

	a.	through a potential difference.
	b.	in a perfect conductor
	c.	in the absence of resistance.
	d.	in a region of infinite resistance.

Several resistors are added in series to a resistor in an already existing circuit. Which of the following best describes the changes that will occur across the original resistor?

	a.	" Voltage will increase, and current will decrease. "
	b.	Voltage and current will decrease.
	c.	Voltage and current will increase.
	d.	" Voltage will decrease, and current will increase."
