Read each question carefully and provide your answers in the space provided. Show all your work for calculations.
1. In a combination circuit, how is the total resistance calculated?
By directly adding all resistances.
By considering series and parallel parts separately.
Using only the parallel resistance formula.
Using only the series resistance formula.
2. What is the main characteristic of current in a series portion of a combination circuit?
It decreases across each resistor.
It is the same through all resistors.
It divides among parallel branches.
It increases across each resistor.
3. In a combination circuit, the voltage drop across parallel components is always the same.
True
False
4. Kirchhoff's current law states that the sum of currents entering a junction equals the sum of currents leaving it.
True
False
5. A combination circuit combines both and components.
6. Ohm's Law states that voltage is equal to current multiplied by .
7. Briefly explain the steps you would take to find the total resistance of a complex combination circuit.
8. Consider the following combination circuit diagram:
a) Calculate the total equivalent resistance of the circuit.
b) Calculate the total current flowing from the power source.
9. Design a combination circuit using at least three resistors (one in series, two in parallel). Draw your circuit diagram and label all components and their resistance values. Then, calculate the total resistance of your circuit.
