When two 10 microfarad capacitors are connected in parallel, what is the net result?

1. 0mf

2. 5mf

3. 10mf

4. 20mf

The correct answer is: 20mf

When capacitors are connected in parallel, their capacitances simply add together to form a net capacitance. This is due to the fact that in a parallel connection, each capacitor is connected directly to the same voltage source, allowing the total charge stored in the system to be the sum of the charges stored in each capacitor. In this case, when you have two capacitors, each with a capacitance of 10 microfarads, you perform the addition as follows: Total capacitance = Capacitance of first capacitor + Capacitance of second capacitor Total capacitance = 10 microfarads + 10 microfarads = 20 microfarads Thus, the net result when these two 10 microfarad capacitors are connected in parallel is 20 microfarads. This is why the answer is correct, as it accurately reflects the principle of parallel capacitance.
