Question

electricity in physics

Answer 1

1.q=12c
t=4s
I=?
I=q/t
 =12/4
 =3 A

2.I=2A
t=60s
q=It
  =2*60
 =120 c

v=3v
w=?
v=w/q
w=vq
  =3*120
 =360J

3.V=220V
  R=1200 ohm
 v=IR
I=V/R
 =220/1200
 =0.18A

Answer 2

1 q =12 c
T=4s
I=?
I=q/ t
=12/4
=3A


2 i=2A
T=60s
Q=it
=2×60
=120 c
V=3v
W=?
W=v q
=360 J
