What is the Weightage of Error Analysis in GATE Exam?

Total 3 Questions have been asked from Error Analysis topic of Electrical and Electronic Measurements subject in previous GATE papers. Average marks 1.00.

The following measurement are obtained on a single phase load; $\mathrm{V}=220\mathrm{V}\pm 1\%,\mathrm{I}=5.0\mathrm{A}\pm 1\%$ and $\mathrm{W}=555\mathrm{W}\pm 2\%$. If the power factor is calculated using these measurements, the worst case error in the calculated power factor in percent is__________. (Give the answer up to two decimal places)

Two resistors with nominal resistance values R_{1} and R_{2} have addictive uncertainties $\triangle$R_{1} and $\triangle$R_{2}, respectively. When these resistances are connected in parallel, the deviation of the error in the equivalent resistance R is

A capacitive voltage divider is used to measure the bus voltage ${V}_{bus}$ in a high-voltage 50 Hz AC system as shown in the figure. The measurement capacitor ${C}_{1}$ and ${C}_{2}$ have tolerances of $\pm 10$% on their normal capacitance values. If the bus voltage ${V}_{bus}$is 100 kV rms, the maximum rms output voltage ${V}_{\mathrm{out}}$(in kV), considering toleance , is _____________.
