When two or more capacitors are connected in series, then their equivalent capacitance ascompared to their individual capacitance will

Explanation

When capacitors are connected in series, the reciprocal of the equivalent capacitance is the sum of the reciprocals of the individual capacitances. This means that the equivalent capacitance is always less than the smallest capacitance in the series. This is because, in a series connection, the charge on each capacitor is the same, but the voltage across each one adds up to the total voltage, resulting in a reduced overall capacitance. Therefore, the correct answer is that the equivalent capacitance will decrease. The other options are incorrect because they either suggest an increase or no change in capacitance, neither of which applies to capacitors in series.
