Question

I need help with these questions. After answering please justify why the answer is correct.

Answer 1

Answer:

1) 2

2) 1

3) 2

4) 2

5) 4

6) 1

Explanation:

1st question

Current is given by rate at which charge flows through a wire which is given as 5 couloumb of charge per second =5A

2nd question

Work done is given by

dU=dV/q

dV=qdU=6(1)=6V because work done to move each couloumb of charge is given as 6J

3rd question

Power is given by P=VI=6(5)=30W

4th question

Total work is given by dU(q) where dU is work to move 1 couloumb of charge

Hence total work =6(5)=30J

5th question

Rate= 5/(1.6x10^-19)=3.1x10^19

6th question

Force(F)=dV(q)/x where x is distance between the points=6/6=1N

Hope this answer helped you :)
