LESSON 04 –
PARALLEL CIRCUITS

 


LESSON WORK

QUESTION #1

Draw a circuit that has three resistors that are in parallel.  The resistances are 100 ohms, 250 ohms and 500 ohms.

 

QUESTION #2

Two 220 ohms resistors are in parallel.  What is the total resistance of the circuit?

 

QUESTION #3

Consider a circuit that has 10 resistors that are all in parallel.  All resistors are 1000 ohms.  What is the total resistance for that circuit?

 

QUESTION #4

Consider the following circuit and solve for all unknowns.

Note: The source is a 9V battery.
