power
The measure of energy consumed by a circuit is called power.
Joules / second = watt. This is a unit of power. In general, in physics, "power" refers to the rate at which energy is transferred or converted.
Power - APEX
One of Kierchieff's laws tell us that the more wattage (energy) consumed by an electrical device in a circuit, the larger the voltage difference that exists across the device and the greater the current flowing through it. The energy consumed is directly proportional to the Impedance of the electrical device but is more importantly proportional to the square of the current. WATTS=VOLTS X AMPERES= RESISTANCE (IMPEDANCE) X AMPERES X AMPERES A Circuit with Current but without resistance would exhibit no energy at all.
When you add a light bulb, you are adding a load, which performs a function - in this case, it converts electrical energy to light and heat energy. When you add an ammeter, most of the time you intend to measure the current in the circuit, which is the function of the ammeter. Thus the two electrical components differ in their function and does different things when added to a circuit.
a single circuit has only one source of energy, like a battery compartment (no matter the amount of batteries) a double circuit has two sources of energy, like two batter compartments
Temperature is a measure of the average kinetic energy of the particles such as the molecules in a gas or a liquid.
temperature is the measure of the average kinetic energy of a substances molecules, though energy is in joules and temperature is in Kelvin.
The measure of the potential energy available in a complete circuit is voltage. Voltage is the potential difference between two points in a circuit that can drive an electric current between those points. It is measured in volts (V).
The measure of electrical energy transferred by electrons in a circuit is typically measured in joules (J) or kilowatt-hours (kWh), which is often used for billing purposes by utility companies.
The measure of potential energy available in a complete circuit is determined by the voltage of the power source, which is typically measured in volts. This potential energy is then utilized by the circuit to drive the flow of electrons and power the various electrical components connected to it.
Voltage
The measurement used to describe how much energy is produced or used during a chemical change is called "enthalpy." It represents the heat exchange that occurs during a reaction and is typically denoted as ΔH. The enthalpy change can be positive (endothermic, absorbs heat) or negative (exothermic, releases heat) depending on the reaction.
The standard unit of electric energy is the Watt Hour.
The standard unit of electric energy is the Watt Hour.
Since power = voltage2/resistance, reducing the resistance will increase the power of the circuit. Incidentally, power is not 'consumed'; it's energy that's consumed.
The amount of oxygen that's consumed when you burn your food is an indirect measure of the amount of energy that's released from the food. Bomb calorimeters are sometimes used to measure the energy content in food.
The number of kilowatts used by a device in one hour. This gives you the rate at which energy is consumed.

A calorie, by definition, is the amount of energy it takes to raise 1 gram of water 1 degree celsius. It is a measure of heat energy. To people, calories are found in foods and drinks, which give us energy. Each calorie is like a measure of potential energy we can then use. Living and exercising thus "burns" calories as we use up the energy we have consumed.
