what is the heating effect of electric current ?write four applications which works​

Answer 1

Explanation:

2. Ohm's law states that at a constant temperature the current flowing through a conductor is directly proportional to the potential difference across its ends.On the last picture the conclusion is that the ratio V/I =constant . Therefore V is directly proportional to I law is obeyed.
