 Practice Problems Sample DC Resistor Network

Directions:On this worksheet you will review the formulas and relationships for resistors wired in series and in parallel. My recommendation is to first build a voltage diagram and an R|I|V|P chart for the circuit and then check your answers by supplying the value specified in each question.  omit
Question 1  In the circuit shown above, the values for each resistor are:

R1 = 5 Ω      R2 = 3 Ω      R3 = 11 Ω      R4 = 8.5 Ω      R5 = 4 Ω      R6 = 6 Ω      R7 = 18 Ω

Based on these values, what would be the total resistance of the combination R2, R3, and R4. omit
Question 2  What is the total resistance of R2, R3, R4, and R5? omit
Question 3  What is the total resistance of R6 and R7? omit
Question 4  What is the total resistance between points b and c? omit
Question 5  What is the total resistance between points a and d? omit
Question 6  If the circuit is connected to a 16.06 volt battery, what is the current through R1? omit
Question 7  What is the current through R2? omit
Question 8  What is the current through R5? omit
Question 9  What is the current through R6? omit
Question 10  What is the voltage drop across R7? omit
Question 11  What is the voltage drop across R3? omit
Question 12  How much power is dissipated through R1? omit
Question 13  How much power is dissipated through R5? omit
Question 14  How much power must be supplied by the battery to run this entire circuit?
