1 orary
Violet
Yellow Brown Gold
(1) 410 Q + 5%
(2) 470 2 + 5%
(3) 470 Q + 10%
(4) 470 2 + 20%​

Answer 1

Answer:

your answer is here in the given image

Explanation:

Answer 2

Resistance = (74 x $10^{1}$ ) ± 5% ohms.

Given:

(As the figure is missing, let us answer the question by following the order of colors given in the question).

Resistance of a carbon resistor in the form of color strips are in the order:

1. Violet

2. Yellow

3. Brown

4. Gold

To Find:

Resistance of the carbon resistor.

Solution:

                          Pre - requisite knowledge:

If a carbon resistor has 4 colored stripes then,

• The first and the second color represents the value.
• The third color represents the multiplier.
• The fourth color represents the tolerance.

In the question,

• First color = Violet

Hence, value = 7

• Second color = yellow

Hence, value = 4

• Third color = Brown

Hence, multiplier = $10^{1}$

• Fourth color = Gold

Hence, tolerance = ±5%

Hence, the total value of resistance = (74 x $10^{1}$ ) ± 5% ohms.

∴ None of the given options are correct.
