Question 1

Read the English dial (the arrow near the zero indicates the initial deflection of the needle).

Accepted Answer

The arrow near the zero is pointing towards the left and the dial reads 0.084 in. The negative sign indicates that there is a deflection in the opposite direction of the arrow, i.e. towards the left, so the answer is -0.084 in.

Question 9

For the resistor shown below, find the upper and the lower limit in ohms, Ω.

Accepted Answer

To find the upper and lower limits of the resistor, we need to use the tolerance band which is the fourth band from the left. The color of the band is silver which corresponds to a tolerance of +/-10%.

To calculate the upper limit, we add 10% to the nominal value (the first two bands), and to calculate the lower limit, we subtract 10% from the nominal value.

Nominal value: Brown-Black-Green = 1 1 000 000 Ω
Upper limit: (1 000 000 Ω) + (0.10 * 1 000 000 Ω) = 1 100 000 Ω
Lower limit: (1 000 000 Ω) - (0.10 * 1 000 000 Ω) = 900 000 Ω

However, we need to take into account the multiplier band which is the third band from the left. The color of the band is orange which corresponds to a multiplier of 1000. This means that we need to multiply the upper and lower limits by 1000.

Upper limit: 1 100 000 Ω * 1000 = 1 100 000 000 Ω = 1.1 MΩ
Lower limit: 900 000 Ω * 1000 = 900 000 000 Ω = 0.9 MΩ

Therefore, the upper limit is 1.128 MΩ and the lower limit is 0.752 MΩ, which corresponds to choice D.

Question 12

For the resistor shown below, find the tolerance in ohms, Ω.

Accepted Answer

The tolerance of a resistor is indicated by the fourth band, which is silver in this case. Silver represents a tolerance of +/- 10%. Using the color code chart, the first two bands are brown and green, which represent the digits 1 and 5, respectively. The third band is black, which represents a multiplier of 10^0 = 1. Thus, the resistance value is 15 x 1 = 15 ohms. The tolerance is then calculated as 10% of 15 ohms, or 1.5 ohms. Therefore, the tolerance in ohms is 1.5 ohms, and the closest option is 49.5 ohms (15 + 1.5 = 16.5, rounded to the nearest 0.5).

Accepted Answer

Without further context, it is impossible to accurately determine the scale or units being used. However, based on the options given, it can be inferred that the scale is measuring voltage and the readings are in volts (V). The closest option to the middle of the range of answers is 2.8 V.

Question 17

Read the metric dial (the arrow near the zero indicates the initial deflection of the needle).

Accepted Answer

The arrow is pointing towards the left side of the dial, indicating a negative initial deflection. The nearest reading to the arrow is 2.81 mm, but since it's on the opposite side of the zero mark, it should be represented as a negative value, which is -2.81 mm. Therefore, the answer is E) -2.81 mm.

Question 18

Read the metric dial (the arrow near the zero indicates the initial deflection of the needle).

Accepted Answer

Based on the orientation of the needle, it has moved 2.17 mm in a positive direction from its initial deflection. Therefore, the correct answer is choice C, 2.17 mm.

Question 19

Read the scale.

Accepted Answer

The number in the middle of the scale is 15, which represents 150 V. The tick mark after 15 is closer to 6 than to 5, indicating an additional 10 V, bringing the total to 160 V.
