Question 29 of 32

The DC power to a load is to be calculated using a voltmeter and ammeter. When correctly connected the voltmeter reads 10V and the ammeter 10A. If both instruments readings are subject to a tolerance of ±10%, the power will be approximately

1. 100W ± 20%
2. 100W ± 15%
3. 100W ± 10%
4. 100W ± 5%
