Question

1. the resistance of a changed value resistor with a 10% tolerance is

a outside ±10% of color code value
b within ±10% of color code value
c equal to color code value
d 0 ohms

Explanation:

Tolerance in resistors indicates the range within which the actual resistance value can vary from the nominal (color - coded) value. A 10% tolerance means the actual resistance is within ±10% of the color - code value. Option a is incorrect as it says outside the range. Option c is wrong because there is a tolerance (variation). Option d (0 ohms) is not related to a 10% tolerance concept.

Answer:

B. within ±10% of color code value
