Explain how would you infer through an experiment that substances generate electric current

I would be explaining about Batteries for use of eletric current.

Explanation:

Take three resistances R1 ,R2, R3 and two ammeters and connect them in series.the ammeter will show in equal reading. This is an experiment to verify that in series that in series connection the current through each component is equal.

What is eletric current? How can you generate it?

Electric current can be generated by moving a metal wire through a magnetic field. This applies both to alternating current (AC) and direct current (DC) electricity. This is a different method than where DC is created by a battery, which uses chemical reactions

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.

i sometimes feel that way too. i feel that i should hurt someone because they hurt me, but i wouldnt do it. that would make things so much worse i have so much experience with this stuff
