Question

five quick questions thx!

1. The total current in to a junction should be equal to:

	A.	the total current out of a junction.
	B.	none of the current out of the junction.
	C.	some of the current out of the junction.
	D.	the negative of the total current out of the junction

2.

How does potential behave at junctions?

	A.	It is applied evenly over every path and with the same potential as the original path.
	B.	Potential can only go to one path from another and does not go through more than one path.
	C.	Some paths have more potential applied than others with the maximum being equal to the original path.
	D.	It is applied evenly over every path and with a potential that is divided by the number of paths.

3.

What is the difference between a capacitor and a battery?

	A.	Capacitors inherently store more charge.
	B.	There is no difference. Capacitors and batteries are the same thing.
	C.	Capacitors release charge over a longer period of time while batteries charge and discharge quickly.
	D.	Capacitors charge and discharge quickly while batteries release charge over a longer period of time.

4.

Using Ohm's Law, keeping the resistance constant and increasing the applied voltage

	A.	does nothing.
	B.	increases the current.
	C.	stops the current.
	D.	decreases the current

5.

When is a device called an Ohmic device?

	A.	No device is an Ohmic device.
	B.	Only when the device obeys Ohm's Law and has a non-linear relationship between potential and current.
	C.	Only when the device obeys Ohm's Law and has a linear relationship between potential and current.
	D.	All devices are Ohmic devices.
