The following measurement are obtained on a single phase load; and . 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 R1 and R2 have addictive uncertainties $\triangle$R1 and $\triangle$R2, 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 $±10$% on their normal capacitance values. If the bus voltage is 100 kV rms, the maximum rms output voltage ${V}_{\mathrm{out}}$(in kV), considering toleance , is _____________.
