1.  Name the following diagram and explain the concept.

come on please answer ​

Answer 1

Answer:

Hence, the three effects of electric current are heating effect, magnetic effect and chemical effect. Note:we have discussed briefly about the effects of current. You need to memorize the effects namely heating effect, magnetic effect and chemical effect.
