#### Answer:

I have created a simple series-parallel DC resistive circuit practice problem below for you.

Try to answer the question and post your answer then I will mark it for you.

Please let me know if you require a complex DC with other circuit components or an ac practice problem then I will give one as well for you.

#### Explanation:

In the diagram below, a 100V DC supply is connected to a resistive series-parallel network as shown.

Calculate the following :

- The total resistance of the circuit.
- The total current
#I_T# . - The branch currents
#I_1 and I_2# . - The potential difference across the
#3,3k Omega# resistor. - The voltage at the point B.
- The voltage
#V_(CA)# . - The power dissipated in the
#2,2 k Omega# resistor. - The amount of charge passing through the
#470 Omega# resistor in 2 minutes. - The cost to operate this circuit for 1 hour if the tariff charges is R1,50 per kWh unit.
