Answer 1

Explanation:

2.True

3 false - it works on principle of magnetic effect of electric current

4.true

electric current

4.true

5.false- it flows from negative to positive

6.flase - only graphite is the non metal which is a conductor

7.false- in series all are dependent

in parallel all are independent
