Question 1 of 27070

If capacitors of 3, 5, and 7 microfarad are connected in parallel, what is the total capacitance?

🔍 Key Concepts

• How capacitance adds in parallel versus in series • Unit consistency: all values are already in microfarads (µF) • Compare the result to the largest single capacitor value to see if your total is reasonable

💭 Think About

• Recall the rule for combining capacitors in parallel. Do you add the values directly, or use reciprocals like with resistors? • If you apply that rule to 3 µF, 5 µF, and 7 µF, what single equivalent capacitor value would store the same total charge at a given voltage? • Once you find the numerical total, is it larger or smaller than each individual capacitor, and does that match the behavior of capacitors in parallel?

✅ Before You Answer

• Confirm you are using the parallel formula for capacitors, not the series formula • Double-check the arithmetic when combining 3, 5, and 7 as required by the parallel rule • Verify that your final answer is greater than 7 µF (the largest individual capacitor) if you’ve combined them correctly in parallel
