Question

A current of 0.2 A flows through a wire whose ends are at a potential difference of 15 V. Calculate: 1) the resistance of the wire, and 2) the heat energy produced in 1 minute

Answer 1

Answer:

i can only answer the first one because i am class 10

Explanation:

1) resistance = V/I

             volt is 20v , current is 0.2a

        substitute

                             =20/0.2

                              =100 ohm

2) i dont know sorry!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
