The capacitor preferred for high-frequency circuit is. Solution: Mica capacitor. Three different capacitors are connected in series, then:. Capacitors are said to be connected in parallel when both of their terminals are respectively connected to each terminal of the other capacitor or capacitors.

Consider two capacitors connected in parallel : i. In this case, the potential difference across the two capacitors is the same, and is equal to the potential differnce between the input and output wires. However, the total stored charge Q is divided between the two capacitors, since it must distribute itself such that the voltage across them is same.

Since, the capacitors may have different capacitances, and , the charges and may also be different. The equivalent capacitance of the pair of capacitors is simply the ratio ,.

The equivalent capacitance of two capacitors connected in parallel is the sum of the individual capacitances. For capacitors connected in parallel, the equation for equivalent capacitance can be generalizes to :. Answer Detailed Solution Below Option 3 : And in the Series circuit , the reciprocal of the equivalent capacitance is the algebraic sum of all the reciprocal of the capacitance. So the correct answer is option 1. Answer Detailed Solution Below Option 1 : parallel combination.

Again in Combination of series and parallel. Series combination will make resultant lesser than original. So only parallel combination will give more capacitance than individual capacitance. Hence the correct answer is option 1. Answer Detailed Solution Below Option 4 : 0.

When combination, where two or more capacitors are connected in such a way that their ends are connected at the same two points and have an equal potential difference across them, is called the parallel combination of a capacitor. All in parallel combination All in series combination Two in series and one in parallel with them Two in parallel and one in series with them. CONCEPT : Combination of capacitors: Parallel combination Series combination When two or more capacitors are connected in such a way that their ends are connected at the same two points and have an equal potential difference for all capacitor is called a parallel combination of the capacitor.

When two or more capacitors are connected end to end and have the same electric charge on each is called the series combination of the capacitor. Hence option 4 is correct.
