Given Information:
Potential difference = V = 450 V
Current = I = 0.80 A
time = t = 1 ms = 0.001 s
Required Information:
(a) Energy = E = ?
(b) Total charge = q = ?
Answer:
(a) Energy = 0.36 J
(b) Total charge = 8x10⁻⁴ C
Explanation:
(a) What is the energy delivered by this pulse
The energy is given by
E = V*I*t
Where V is the potential difference, I is the current flowing and t is the time.
E = 450*0.80*0.001
E = 0.36 J
(b) what is the the total charge that flows?
We know the current is the rate of charge
I = q/t
q = I*t
q = 0.8*0.001
q = 0.0008
q = 8x10⁻⁴ C
