already exists as an alternate of this question.

Would you like to make it the primary and merge this question into it?

exists and is an alternate of .

Usually we use a mechanical or electrical meter. Gas supplies can simply drive round a counter. Electricity can be measured in several ways, for instance by using part of it to turn a disc which in turn drives a counter. Essentially we measure how much power we use and for how long. The unit is usually kilowatt-hours.

What laboratory methods are used to determine the energy content of foods?

calorimeter . although not most accuratethe simplest way to test the energy content of foods is using a calorimeter, this is basically a insulated copper beaker filled wit

What is the formula you use to determine the gravitational potential energy of an object?

Weight x Height = Potential energy The units and the calculation are the same as for work. Work is force through a distance. Get the weight in the SI by multiplying the mass

What is formula you use to determine the gravitational potential energy of an object?

PE = mgh, that is, mass x gravitation x height. Or simply weight times height, since weight is already equal to mass times gravitation.\n\n. On Earth, you would usually use 9

Why a Gm counter is not useful for determining absorbed energy in a gas?

The Geiger-Meuller detector operates in avalanche mode, meaning that each ionization interaction results in a full pulse on the detector. Each pulse, then, is not proportiona

What factors determine whether a source of energy is useful?

1 Whether it is a renewable resource, (a resource that naturally renews itself, like solar power or wind) 2 Its cost effectiveness (does it help reduce the cost of energy in

How do you determine the amount of electrical energy used by a device?

Measure the current flowing through the device and the voltage across it; multiply the current by the voltage to get the power in Watts. Watts = Volts x Amps ; Watts = Amps
