To find the current (A) given the charge (Q) and voltage (U), we can use Ohm's Law formula:

I = Q / t

Where:
I = current (A)
Q = charge (Coulombs)
t = time (seconds)

Given:
Q = 5•10^-8 Coulombs
U = 10^3 Volts

We can rearrange the formula to solve for current (I):

I = Q / t
I = U / R (since R = V/I and U = V)

Now we need to find the resistance (R) using the formula:

R = U / I

Substitute the values:

R = 10^3 / 5•10^-8
R = 2•10^10 ohms

Now we can find the current by rearranging the formula:

I = U / R
I = 10^3 / (2•10^10)
I = 5•10^-8 A

Therefore, the current is 5•10^-8 Amperes.
