Question

An electrical parts manufacturing company produces resistors of

resistance 700 ohms and they quarantee that the variations will
stay within a range of +5%. Which equation can be used to find
the lowest and highest resistance that can be achieved?
x+700=5
x+700=35
Ix-700=5
x-7001=35

Answer 1

d. x-700=35

Explanation:

The statement says that the variations will stay within a range of +5%, so the resistance can be increased by 5% of 700 ohms. To find the highest resistance that can be achieved, you can use the formula:

x = 700 + (700 * 5%) = 700 + 35 = 735 ohms

To find the lowest resistance that can be achieved, you can subtract the same percentage (5%) of 700 ohms:

x = 700 - (700 * 5%) = 700 - 35 = 665 ohms

So the lowest and highest resistance that can be achieved are 665 ohms and 735 ohms respectively.
