What is the change in potential going from Point B to Point A?

 

A.

B.

C.

 

D.

 

 

The Current in this circuit will go clockwise so Point A will be higher in potential than Point B.  So we will have a positive change in potential.

 

First find the current.

 

 

The voltage drop across the  resistor is found from Ohm’s Law

 

 

So Correct Answer is A !

18

In the circuit above, what is the current  as drawn in the circuit?

 

A.

B.

C.

 

D.

 

 

Current will be negative as the current should go from top of resistor down as the top is connected to the + part of the power supply.  The value we can get from Ohm’s Law.

 

 

So Correct Answer is C !

19

In the circuit shown above, the following currents were determined

 

 

What is the change in voltage going from point A to point C?

 

A.

B.

C.

 

D.

 

 

Do a voltage walk from A to C:

 

 

 

So the Correct Answer is D !

How much energy is stored on the  capacitor once the two capacitors have been connected long enough to be fully charged by the power source?

 

A.

C.

 

 

 

 

B.

D.

 

Once the capacitor is fully charged,

 

 

So Correct answer is B !
