1 A switch has been opened after 35ms of operation This mean

A switch has been opened after 3.5ms of operation. This means 8mA current flowed in a 60 H inductor circuit for this time duration. What EMF is induced in the inductor?

1.	A switch has been opened after 3.5ms of operation. This means 8mA current flowed in a 60 H inductor circuit for this time duration. What EMF is induced in the inductor?

E=L di / dt

= 60(8*10^-3/3.5*10^-3)

= 60(8/3.5)

= 137.14 Volts
