Circuits

Question 1

In series

Answer 1

Add Resistors to make equivalent resistance

Question 2

In Parallel

Answer 2

1/R = 1/R1+1/R2

Question 3

Thevenin Equivalent

Answer 3

Pick each node, take the voltage (starting always from the node) and divide by the resistance.

Question 4

Inductors

Answer 4

Add like resistors (in series, just add. in parallel L1*L2/(L1+L2))

Question 5

Impedance diagram

Answer 5

Add together, point sides in the magnitude and direction
