calculate:An elcetric lamp is rated 240V and 40W. What is the cost of running the lamp for 62 hours if the elctricity authorities charges #2.50k per KWH

Total cost = #6.2

Explanation:

Given the following data;

Voltage = 240 V

Power = 40 W

Time = 62 hours

Cost = #2.50

To find the cost of running the lamp for 62 hours;

First of all, we would determine the energy consumption of the electric lamp

Energy consumption = power * time

Energy consumption = 40 * 62

Energy consumption = 2480 Watt-hour = 2.48 Kwh (1 Kilowatts is equal to 1000 watts).

Next, we would determine the cost of running the lamp;

Total cost = energy consumption * cost

Total cost = 2.48 * 2.50

Total cost = #6.2

answer: the direction of the wind is expressed as the direction from which the wind is blowing. for example, easterly winds blow from east to west, while westerly winds blow from west to east.
