Question

for correct answer I will mark as brainlist​

Answer 1

Answer:

7 )a

potential diff = work done /charge

1v= 1j/1c

d) all of these

pd = IR , WD/C , V

9) drift speed of electrons in copper wire is 0.1 cms^-1

10)

2/3 A because resistance and current are inversely proportional

a) ammeter is connected in series and voltmeter in parallel

12) 2.5 ohm

R =V/I

= 5/2= 2.5 ohm
