mili = 10^-3 ( jedna tysięczna)
mikro = 10^-6 ( jedna milionowa)
q = 20 mC = 20 *10^-3 C = 2 *10 *10^-3 = 2 *20^-2 C
t = 200 mikros = 200 *10^-6 C = 2 *10^2 *10^-6 s = 2 *10^-4 s
I = ?
I = q / t
I = 2 *10^-2 C / 2 *10^-4 s
I = 10^2 A = 100 A
q = 20 mC (milikulombów) = 20 * 0,001C = 0,2 C
1 mC = 0,001 C
t = 200 us (mikrosekund) = 200 * 0,000001s = 0,002 s
1 us = 0,000001 s
