Answer:
a) 360W
b) 0.36 J
c) 0.0008 C
Step-by-step explanation:
1 ms = 0.001 s
a) The power is the product of current and potential difference
P = VI = 450 * 0.8 = 360 W
b) The energy is the power multiplied by time duration
E = Pt = 360*0.001 = 0.36 J
c) The total charge is the current multiplied by the time duration
C = It = 0.8*0.001 = 0.0008 C
