A capacitance of 2 μF is required in an electrical circuit across a potential difference of 1.0 kV. A large

number of 1μF capacitors are available which can withstand a potential difference of not more than 300 V.
The minimumnumber ofcapacitors required to achieve this is ??

Heya........!!!!

A diagram would be needed for this question , to get out the Perfect answer but nevermind

Here's ur answer ⬇⬇

=> First of all We need to take out Potential on one Capaciter i.e :

=> Potential on each capacitor V = 1000/n
Here V = 300

So ,,

=> 1000/n = 300 = n = 1000÷300

=> n = 10/3 = 4 ( Approximately )
=> C( eq ) = C/n × m

Substituting the values of C(eq) and C we get ,,

(( n capacitors ,, m rows ))

=> 1/n × m = 2

Therefore ,,

m = n × 2 = 4 × 2 = 8
m = 8 ( 8 rows )

➡➡ Minimum number of capacitor = 8 × 4 =

♦ 32 capacitors . is the required answer .

Hope It Helps You ^_^
