A transformer has the ability to change an ac supply of 2kW,240V to 60V. a) what is the turns ratio of this transformer. b) how large is the output current if the transformer is 100% efficient. c) what will be the output current if there is a 10% power loss in the transformer

This is what a calorimeter is used for simpler ex, to measure calories in food.

The answer is -6hope this

Answer: 1.4 seconds which is the third optionexplanation: current is defined as the flow of charge per timetherefore, the equation that relates current, charge and time can be expressed as follows: i = δq / δtwhere: i is the current given = 1.8 ampereδq is the charge given = 2.5 coulombδt is the time required for the flow of the given charges to give the 1.8 ampere.substitute with the givens in the above equation to get the time as follows: 1.8 = 2.5 / δtδt = 2.5 / 1.8 = 1.38888 which is approximately 1.4 secondshope this was !
