Q1: What value of a 1.3 k resistor as measured by a digital voltmeter would be considered within tolerance?

ANS:B - 1235

In normal resister has plus or minus 5% tolerance.

So 1.3k= 1300*5%= 65 ohms (plus or minus.)

According to this question it will match with answer if we minus the 65 ohms. 1300-65=1235 ohms
