Answers
Answer:
When a current flows through a conductor, heat energy generates in the conductor. The heating effects of electric current depend on three factors:
The resistance of the conductor. A higher resistance produces more heat.
The time for which the current flows. The longer the time the amount of heat production is high.
Higher the current the amount of heat generation is also large.
Hence the heating effect produced by an electric current, I through a conductor of resistance, R for a time, t is given by H = I2Rt. This equation is the Joule’s equation of electrical heating.
Answer:
Heating effect, Chemical effect and magnetic effect
Explanation:
when electric current passes through a conductor the electrons collide (doing work on order to move forward) with the conductors atoms and this causes generation of heat.
Acids, bases and salts when dissolved in water produce ions which get attracted to oppositely charged electrodes connected to a cell's terminals and this causes electrons to travel along with the ions thus depositing the ions on their oppositely charged electrodes.
when an electric current passes through a conductor the magnetic field related to the conductor changes as long as there is a change going on in the amperage of the current...( while it is building up or scaling down) . Hence the conductor begins to act like a magnet when placed in a magnetic field.
