The voltage across a lamp is `(6.0 +- 0.1) V` and the current passing through it is `(4.0 +- 0.2)` ampare. Find the power consumed by the lamp.

The voltage across a lamp is (6.0pm0.1)V and the current flowing through it is (4.0pm0.2)A . Find the power consumed with maximum permissible error in it.

The voltage across a lamp is 6.82 V when the current passing through it is 4.1 A. Find the power consumed to appropriate significant figures.

The voltage across a lamp, is 6.32V when the current passing through it is 3.4 A. Find the power consumed to appropriate significant figures.

The voltage across a resistor is 8.0pm0.2 volt and the current through it is (3.8pm0.1) ampere. What is the power consumed? The errors quoted are the standard deviations in the measurements. [Hint : Use W = VI and ((sigmaw)/(W))^(2)=((sigmav)/(V))^(2) +((sigmal)(I))^(2) ]
