I am not quite sure about the experimental setup. But in general, the power (not energy) taken out by the load and any resistors is taken out of the source. It is impossible to take out more or less power than is generated by the source. The way this works is as follows: the load has a certain resistance; as a result, if a certain voltage is applied, a certain current will flow (use Ohm's Law to calculate the current). This same current flows through the source (Kirchhoff's Current Law), and if there are no additional resistances, the voltage will also be the same (Kirchhoff's Voltage Law). Therefore, the power will be the same.

What kind of energy does an unlit match have?
Potential energy, released when the match is struck.
Describe the energy transformations that happen hen you strike a match?
When you strike a match, first the energy is chemical because of the chemcial on the tip of the match. Then, it is mechanical because your hand moves. Then it is thermal because the match lights on fire.
What load impedance Z will result in maximum power transfer from an electric source with an internal impedance of r?
For maximum power transfer, source resistance should match load resistance and source reactance should match load reactance with the opposite sign (so if the load is capacitive, the source should be inductive).
What forms of energy happen when you strike a match?
When you strike a match, mechanical energy is used to move the matchstick against the rough striking surface. This generates heat energy due to friction, which ignites the combustible chemicals on the match head. The chemical reaction releases thermal energy and light energy in the form of a flame.
What is the source of activation energy that ignites a strike-anywhere match?
The source of activation energy that ignites a strike-anywhere match is friction between the match head and the matchbox, which creates enough heat to ignite the match head. When you strike the match against the rough surface on the matchbox, the friction generates heat that is sufficient to initiate the chemical reaction in the match head, leading to ignition.
What are the energy transformations in striking a match?
When striking a match, the chemical energy stored in the match-head is transformed into heat and light energy.
What is the energy transformations in a striking match?
When a match is struck, mechanical energy from the friction between the match head and the striking surface is converted into thermal energy from the heat production that ignites the match head. This thermal energy is then transformed into light and heat energy as the match continues to burn.
What is the conclusion for a hydro-electric power?
Hydropower is the cheapest way to generate electricity today. No other energy source, renewable or nonrenewable, can match it. Producing electricity from hydropower is cheap because, once a dam has been built and the equipment installed, the energy source-flowing water-is free. Although Hydropower does present a few environmental problems the inherent technical, economic and environmental benefits of hydroelectric power make it an important contributor to the future world energy mix,
When a person strikes and lights a match potential energy in the match is transformed into which types of energy?
When a person strikes and lights a match, potential energy in the match is transformed into thermal energy (heat), light energy (the flame), and chemical energy (burning of the matchstick).
Where does the energy come from to light a match?
Chemical energy, stored in the match.
What type of energy does a match stick have before it begins to burn?
A match stick typically contains potential energy in the form of chemical energy stored in the match head and the striking surface. When the match is struck, this potential energy is converted into thermal energy and light as the match ignites and burns.
What energy transformation occurs when a match is being lit?
Well, honey, when you strike that match, you're converting the potential energy stored in the match head into thermal energy through friction. As the match ignites, the chemical potential energy in the match head is transformed into heat and light energy. So, basically, you're turning a boring old match into a fiery little showstopper.
