You have capacitors rated for 250 Volts and you need the combination to have voltage rating of 1000 volts. Hence it is obvious that you should connect four numbers in series. For such a series connection, effective capacitance is  2 micro farad, because 1/Ceffective = 1/C1 + 1/C2 +1/C3 +1/C4 = 1/8 + 1/8 + 1/8 + 1/8 = 1/2.
 Therefore Ceffective  = 2 microfarad. Hence the series combination is equivalent of 2 mcrofarads, 1000 Volts. To have capacitance of 16 microfarads, you should connect 8 such series combinations in parallel, because in parallel combination, effective capacitance is equal to summation of each capacitor.  Hence capacitors required will be:
4 nos for each series combinations × 8 such combinations = 32 capacitors...

To form a composite 16 micro farad 1000 volt capacitor from a supply o...
Calculating the number of capacitors required:

To form a composite capacitor with a capacitance of 16 micro farads and a voltage rating of 1000 volts, we need to determine the minimum number of capacitors required.

Given:
- Capacitors available have a capacitance of 250 volts and a voltage rating of 250 volts.

To calculate the number of capacitors required, we can use the formula:

Total capacitance = (Individual capacitance) x (Number of capacitors)

Given that the total capacitance required is 16 micro farads, and the individual capacitance of each capacitor is 250 volts, we can substitute these values into the formula:

16 micro farads = 250 volts x (Number of capacitors)

Solving the equation:

To solve for the number of capacitors, we need to rearrange the equation:

(Number of capacitors) = (Total capacitance) / (Individual capacitance)

Plugging in the values:

(Number of capacitors) = 16 micro farads / 250 volts

Converting the units to maintain consistency:

(Number of capacitors) = (16 x 10^-6 farads) / (250 volts)

(Number of capacitors) = 6.4 x 10^-8 farads/volt

Calculating the number of capacitors:

To determine the minimum number of capacitors required, we need to divide the total capacitance by the individual capacitance.

(Number of capacitors) = (6.4 x 10^-8 farads/volt) / (250 volts)

(Number of capacitors) = 2.56 x 10^-10 farads/volt

Since the number of capacitors cannot be a fraction or a decimal, we need to round up to the nearest whole number. Therefore, the minimum number of capacitors required is 3.

Final Answer:

The minimum number of capacitors required to form a composite 16 micro farad 1000 volt capacitor from a supply of identical capacitors marked as 250 volt micro farads is option A. 40.

Similar Class 12 Doubts

Read the following text and answer the following questions on the basis of the same: Capacitor Colour Code: Capacitor values as written on small capacitors are sometimes misleading. Letters like p (pico) or n (nano) are used in place of the decimal point to identify its position and the value of the capacitor. For example, a capacitor labelled as n33 = 0.33nF, 8n2 = 8.2nF, 22n = 47nF and so on. Sometimes capacitors are marked with the capital letter K to signify a value of Kilo pico-Farads. As for example, a capacitor with the markings of 100K would be 1000 × 100 pF = 100 Kpf = 100 nF. Sometimes, a three letter code consists of the two value digits and a multiplier. For example, the digits 471 = 47 × 10 = 470 pF, 332 = 33 × 100 = 3300 pf. To reduce these confusions an International colour coding scheme was developed almost the same as that of resistance colour code.The value obtained from colour code is in pf.68k is written on a capacitor.

Read the following text and answer the following questions on the basis of the same: Supercapacitor: Super capacitor is a high capacity capacitor with a capacitance value much higher than normal capacitors but with lower voltage limits. Such capacitors bridges the gap between electrolytic capacitors and rechargeable batteries. In automobile, bus, train, crane, elevator such capacitors are used for regenerative braking, short term energy storage or burst-mode power delivery. Super capacitors have many advantages over batteries: they are very low weight and generally don't contain harmful chemicals or toxic metal. They can be charged and discharged innumerable number of times without ever wearing out. The disadvantage is that super capacitors aren’t well-suited for long-term energy storage. The discharge rate of super capacitors is significantly higher than lithium-ion batteries; they can lose as much as 10-20% of their charge per day due to self discharge.Self-discharge rate of Supercapacitors
