RC Circuit Fundamentals
Build the model
Answer Questions 1–3 using the written information in this worksheet. No circuit schematic is needed.
- It stores energy in the electric field between its plates.
- It creates charge from the supply.
- It keeps the current constant throughout charging.
- It converts all supplied energy into sound.
Calculate and predict
A student uses a 12.0 V supply, a 47 kΩ resistor and a 220 μF capacitor. Assume an ideal circuit unless stated otherwise.
Check the evidence
The student records the capacitor voltage while charging from a 12.0 V supply.
