The voltage across a lamp is (6.0 0.3) volt and the current passing through it is (4.0 0.1) ampere. The power consumed in watt will be (using percentage error)

Options

  1. A(24.0 1.8)
  2. B(24.0 0.75)
  3. C(22.0 0.4)
  4. D(18.0 0.4)

Correct answer

A. (24.0 1.8)

Step-by-step solution

Power is given by P = VI Substituting the given values: P = 6.0 4.0 = 24.0 W The relative error in power is given by: P P = V V + I I P 24.0 = 0.3 6.0 + 0.1 4.0 P 24.0 = 0.05 + 0.025 = 0.075 P = 24.0 0.075 = 1.8 W The power consumed is (24.0 1.8) W. Answer: (24.0 1.8)
