When capacitors are connected in series, the total capacitance can be calculated using the formula:
[ \frac{1}{C_{total}} = \frac{1}{C_1} + \frac{1}{C_2} + \frac{1}{C_3}
]
In this case, the three capacitors have capacitances of 0.05 µF, 20 µF, and 40 µF. Plugging in these values into the formula gives:
[ \frac{1}{C_{total}} = \frac{1}{0.05} + \frac{1}{20} + \frac{1}{40} ]
Calculating each term separately:
For the 0.05 µF capacitor: [ \frac{1}{0.05} = 20 ]
For the 20 µF capacitor: [ \frac{1}{20} = 0.05 ]
For the 40 µF capacitor: [ \frac{1}{40} = 0.025 ]
Now, adding these values together:
[ \
