Given change of current di/dt = 20*10^-3amperes./10^-6 s
Inductance = 8*10^-6henry.
To find voltage = L*di/dt = 8*10^-6*20*10^-3/10^-6
= 160*10^-3 v.
= 160 milli volts.
Inductance = 8*10^-6henry.
To find voltage = L*di/dt = 8*10^-6*20*10^-3/10^-6
= 160*10^-3 v.
= 160 milli volts.

Given inductance = 8*10^-6henry. { Henry symbol is H }
and also di/dt means given change of current 20*10^-3amperes.
Current is measured in amperes. Inductance is measured in henry.
To find the voltage L *di/dt = 8*10^-6*20*10^-3/10^-6
= 160*10^-3
= 160mv
voltage is measured in volts.
