Question

Q. A resistor of 10Kohm having tolerance of 10% is connected in series with another resistor of 20Kohm having tolerance 20%.The tolerance of combination will be
​

Answer 1

Answer:

In series effective resistance =R

S

=(10kΩ±10%)+(20kΩ±20%)=(30kΩ±30%)

∴ Tolerance of the combination =(±30%)
