The following measurements are obtained on a single phase load: $$V = 220 V$$ $$\pm$$$$1$$%. $${\rm I}$$$$= 5.0$$ $$A$$ $$\pm \,1$$% and $$W=555$$...
Two resistors with nominal resistance values $${R_1}$$ and $${R_2}$$ have additive uncertainties $$\Delta {R_1}$$ and $$\Delta {R_2},$$ respectively...
A capacitive voltage divider is used to measure the bus voltage Vbus in a high-voltage 50Hz AC system as shown in the figure. The measurement capacito...
Fringing in capacitive type transducer can be minimized by providing a _________
A precise measurement guarantees accuracy of the measured quantity.
A metal strain gauge has gauge factor of two, it's nominal resistance is $$120$$ Ohms. It is undergoes a strain of $${10^{ - 5}},$$ the value of chan...
A resistance is measured by the voltmeter- ammeter method employing d.c. excitation and a voltmeter of very high resistance connected directly across ...

## Marks 2

Suppose that resistors $${R_1}$$ ܴand $${R_2}$$ ܴare connected in parallel to give an equivalent resistor $$R.$$ If resistors ܴ$${R_1}$$ and $${R_2}$$...
A variable $$'w'$$ is related to three other variables $$x, y, z$$ as $$w=xy/z.$$ The variables are measured with meters of accuracy$$\pm$$ $$0.5$$%...
The set-up in the figure is used to measure resistance $$R$$. The ammeter and voltmeter resistances are $$0.01$$$$\Omega$$ and $$2000$$$$\Omega$$, r...
Resistances $${R_1}$$ and $${R_2}$$ have, respectively, nominal values of $$10\Omega$$ and $$5\Omega ,$$ and tolerances of $$\pm 5\%$$ and $$\pm 1... Two$$100\mu A$$full scale$$PMMC$$meters are employed to construct a$$10V$$and a$$100V$$full scale voltmeter. These meters will ... In the circuit shown in fig. For measuring resistance$$'R'$$if the ammeter indicates$$1A$$and the voltmeter indicate$$100V, then the value...
