Question

Two capacitors with capacitance values C_1=2000±10 pF and C_2=3000±15 pF are connected in series. The voltage applied across this combination is V=5.00±0.02 V. The percentage error in the calculation of the energy stored in this combination of capacitors is __________.

MARKS Content Team · Accepted Answer

Correct answer: 1.3. For the purpose of calculation of error, fundamental formula is considered 1/C=1C_1+1C_2⇒C=1200 pF -dC/C12=-dC_1/C12-dC_2/C22 dC=6 pF Equivalent capacitance =1200±6 pF E=1/2 CV^2 (dE/E=dC/C+2dV/V)×100 =1.3%
