Combination of Capacitors:
1. Series Combination:
When capacitors are connected in series, the reciprocal of the total capacitance is equal to the sum of the reciprocals of the individual capacitances.
Effective Capacitance = 1 / (1/9 + 1/9 + 1/9) = 3 micro Farad
2. Parallel Combination:
When capacitors are connected in parallel, the total capacitance is equal to the sum of the individual capacitances.
Effective Capacitance = 9 + 9 + 9 = 27 micro Farad
3. Combination of Series and Parallel:
Combining the capacitors in both series and parallel will involve multiple steps of calculation based on the configuration of the circuit.
For example, connecting two capacitors in series and then connecting the third capacitor in parallel to the combination will result in a different effective capacitance compared to connecting all three capacitors in parallel first and then in series.
The effective capacitance for each case will vary depending on the specific arrangement of series and parallel connections.
In conclusion, the three capacitors of 9 micro Farad can be combined in multiple ways such as series, parallel, or a combination of both. The effective capacitance in each case will differ based on the configuration of the circuit. It is important to understand the rules of series and parallel combinations to accurately calculate the total capacitance in such circuits.
