Midterm 1

Question 1

You can have 0 current but

Answer 1

also have some voltage as long as there’s a voltage source.

Question 2

Similar to thevenin 2 nodes can have

Answer 2

the same voltage as long as one has an open circuit

Question 3

Any point on the circuit connected to ground

Answer 3

is 0 other than sources

Question 4

Voltage divider only works

Answer 4

if the circuit is in series

Question 5

KCL

Answer 5

All currents going into a node & coming out of one must be = 0

Question 6

Parallel resistors have the same

Answer 6

Voltage but different currents. Series resistors do not.

Question 7

KVL

Answer 7

The sum of all voltages in a loop must be equal to zero

Question 8

How do we know if the current flowing in the resistor is the same as Isc

Answer 8

If the resistor load or terminals a and b are parallel to the first resistor then that resistor’s current = Isc and we can then replace it.

Question 9

How do we know if we should create a new box or line across the terminals a and b for Norton’s theorem?

Answer 9

If the terminals a and b aren’t connected to the same resistors or don’t lie on the same line then we can draw a line to both terminals.
