Test: Electrical & Electronic Measurements- 1 - Question 3

### A 50 V range voltmeter has a sensitivity of 40 KΩ/V. The total resistance of the voltmeter is – (in MΩ)

Detailed Solution for Test: Electrical & Electronic Measurements- 1 - Question 3

Given that,
Voltage range = 50 V
Sensitivity = 40 KΩ/V
Total resistance = Sensitivity × Voltage range
= 40 KΩ/V × 50 V
= 2000 KΩ
= 2 MΩ

*Answer can only contain numeric values
Test: Electrical & Electronic Measurements- 1 - Question 4

A voltmeter has 100 scale divisions and can measure up to 200 V. Each division can be read up to 1/5 division. The resolution of the voltmeter is – (in V)

Detailed Solution for Test: Electrical & Electronic Measurements- 1 - Question 4

100 divisions = 200 V
1 divisions = 2 V
1/5 division = 0.4 V
Resolution = 0.4 V

Test: Electrical & Electronic Measurements- 1 - Question 5

A resistance is determined by voltmeter ammeter method. The voltmeter reads 100 V with a probable error of ±12 V and ammeter reads 10 A with a probable error of ±2 A. Determine the probable error in the computed value of resistance

Detailed Solution for Test: Electrical & Electronic Measurements- 1 - Question 5

We have resistance
Weighted probable error in the resistance due to voltage is,

Weighted probable error in the resistance due to current is,

Probable error in computed resistance is,

Test: Electrical & Electronic Measurements- 1 - Question 6

A voltage reading is to be taken across the load Resistor R­L in the circuit shown below. A voltmeter with a sensitivity 10 kΩ/V and a guaranteed accuracy of ± 5 % at full scale is to be used on its 20 V range. The maximum voltmeter reding that could be expected is __ (in V)

Detailed Solution for Test: Electrical & Electronic Measurements- 1 - Question 6

Sensitivity of voltmeter = 10 kΩ/V
Full scale reading (VFSD) = 20 V
Internal resistance of voltmeter (Rv) = 10 kΩ/V × 20 V
= 200 kΩ
By voltage division,

Guaranteed accuracy of meter = ± 5% at FSD.
V0 = 10 ± (5% of 20) = 10 ± 1 = 9 to 11
Maximum voltmeter reading = 11 V.

Test: Electrical & Electronic Measurements- 1 - Question 7

The resistance is measured by the voltmeter ammeter method the voltmeter reding is 50 V on 100 V scale and ammeter reading is 50 mA on 100 mA scale. If both the meters are guaranteed for accuracy with 2% of full scale, what is the limit within which resistance (in Ω ) can be measure?

Detailed Solution for Test: Electrical & Electronic Measurements- 1 - Question 7

V = 50 ± (2% of 100 V)
Im = 50 × 10-3 ± (2% of 100 mA)

Rm = 103 ± 4% = 1000 ± 40
= 960 Ω to 1040 Ω
Limit = 80 Ω

Test: Electrical & Electronic Measurements- 1 - Question 8

A 150 ± 10% Ω resistor is connected to the terminals of a power supply operating at 200 ± 0V. If the resistor varies over the range ± 10% of its expected value, what is the range of error in this current.

Detailed Solution for Test: Electrical & Electronic Measurements- 1 - Question 8

Given voltage range, V = 200 ± 0 V
Given resistor range, R = 150 ± 10% Ω
= [150 – 10%, 150 + 10%]
= [150 – 15, 150 + 15]
= [135, 165] Ω
When R = 135 Ω

= 11.13%
When R = 165 Ω

= -9.07%
Range of error in the current = -9.07% to 11.13%

Test: Electrical & Electronic Measurements- 1 - Question 9

Which one of the following statement is not correct?

Detailed Solution for Test: Electrical & Electronic Measurements- 1 - Question 9

It is possible to have precise measurements which are not accurate. we can get precise results which may not accurate.
So option (a) is not correct

Test: Electrical & Electronic Measurements- 1 - Question 10

The current I flowing through a resistance of value 100 Ω ± 0.2% is I = 4A ± 0.5% the uncertainty in measurement of power is

Detailed Solution for Test: Electrical & Electronic Measurements- 1 - Question 10

When many variables are in valued is done on the same basis as is done for error analysis when the result are expressed as standard deviation or probable errors.
Let x = F(x1, x2, x3 …..)
Wx1, Wx2, …. Wxn be the uncertainties of x1, x2, … xn then uncertainty of x is given by

Calculation:
R = 100 ± 0.2% = 100 ± 0.2
I = 4 ± 0.5% = 4 ± 0.2
P = 100 × 42 = 1600 W
