GATE 2024 Electrical & Electronic Measurements Foundation Quiz 57

A voltmeter reads 110.75 volts. What could be the true value of voltage for an error of –0.25 volts.

From the two ammeters, we get I = 10A (±10%) and I₂ = 8A (±5%).

If I₁ = I – I₂. Estimate the relative error in the value of I₁ (in % estimated

value)_____?

(0 – 40) Amp ammeter has a guaranteed accuracy error of 2% of the full scale reading. If the current measured by this instrument is 10A, the value of relative limiting error in percentage will be

A full wave rectifier instrument calibrated on sine wave indicating 3.33 V for a triangular input. What will be the % error in the circuit ?

A Resistor having the nominal value of 400 ± 0.8%. If the voltage across the resistor is found to be 220V ± 2%. The power consumed in resistor is calculated as . What will be the uncertainty in the determination of power measured across the resistor?
