Answer 2

Hey Dear,

◆ Answer -

Tolerance of the combination will be 5 %.

◆ Explaination -

Each 100 ohm resistance have tolerance of 5%. i.e. 5 ohm.

Total tolerance of 4 such resistances is 4 × 5 = 20 ohms.

Total resistance of combination is 4 × 100 = 400 ohms.

Tolerance of the combination will be -

Tolerance = 20 / 400 × 100 %

Tolerance = 5 %

Therefore, tolerance of the combination will be 5 %.

Hope this helps you. Thanks for asking..
