Read each question carefully and provide your answers in the space provided. Show all your work for calculations.
1. A combination circuit contains both and components.
2. In a series part of a combination circuit, the current is through all resistors.
3. In a parallel part of a combination circuit, the voltage is across all resistors.
4. Which of the following is true about the total resistance in a combination circuit?
It is always the sum of all resistances.
It is always less than the smallest resistance.
It depends on how the components are arranged.
It is always higher than the largest resistance.
5. If resistors are connected in parallel, adding more resistors will:
Increase the total resistance.
Decrease the total resistance.
Have no effect on total resistance.
Only affect the current, not resistance.
6. Draw a simple combination circuit with one resistor in series with a parallel combination of two other resistors. Label all components (power source, resistors).
7. Consider a circuit with a 12V battery. Resistor R1 (4 Ω) is in series with a parallel combination of R2 (6 Ω) and R3 (3 Ω).
a) Calculate the equivalent resistance of the parallel combination (R2 and R3).
b) Calculate the total equivalent resistance of the entire circuit.
c) Calculate the total current flowing from the battery.
