Question

The four capacitors, each of 25 muF are connected as shown in figure. The DC voltmeter reads 200 V. the change on each plate of capacitor is

  1. plus-or-minus 2 cross times 10 to the power of negative 3 end exponentC    
  2. plus-or-minus 5 cross times 10 to the power of negative 3 end exponentC    
  3. plus-or-minus 2 cross times 10 to the power of negative 2 end exponentC    
  4. plus-or-minus 5 cross times 10 to the power of negative 2 end exponentC    

The correct answer is: plus-or-minus 5 cross times 10 to the power of negative 3 end exponentC


    Charge on each plate of each capacitor
    Q equals plus-or-minus C V equals plus-or-minus 25 cross times 10 to the power of negative 6 end exponent cross times 200
    equals plus-or-minus 5 cross times 10 to the power of negative 3 end exponent C
