|
|
| • | When switch opens
in an RL circuit |
|||||||||
| – | Energy is
released in a short time |
|||||||||
| – | This may create a
large voltage |
|||||||||
| – | Induced voltage
is called an inductive kick |
|||||||||
| • | Opening of
inductive circuit may cause |
|||||||||
| voltage spikes of
thousands of volts |
