Series Circuits Practice Problems

1. Given the series circuit below find the following unknown values.

Show all your work step-by step

GIVEN FIND FIND
ITotal = 2 A  VTotal= ? RTotal = ?
V1 = 2 V 1 = ? V2 =
R2 = 10 Î© I1 = ? I2 = ?

 

2. Calculate the total power used by the above circuit

3. Add a third resistor in series to the above circuit. 

The value of this resistor is R3 = 10 ohms.  

The value of the current stays the same (ITotal = 2 A). 

Recalculate all the values in the table above and the value of V3 and I3.
