The voltage across a lamp is V = (6.0 + - 0.1) volt and the current passing through it I = (4+ - 0.2) ampere. Find the power consumed by the electric lamp. Given Power = V*I |

Answer» Answer: The power consumed by the lamp is, \bold{P=(24 \PM 1.6) W}P=(24±1.6)W Here is the solution: The voltage across a lamp is V = (6.0+_ 0.1) v The CURRENT passing through it is (4+-0.2) A By using formula, Power = V*I P = 6*4 = 24 Watt dP = P(dV/V + dI/I) dP = 24*(0.1/6 + 0.2/4) dP = 1.6 Therefore, answer:- Power consumed = (24 ± 1.6) Watt Explanation:I hope it is helpful to you and mark me as brainliest |
