Question { NTPC, 54039 }

why free wheeling diode is connected across inductive load

Answer

Free wheeling diodes are used whenever inductive loads are
switched off by silicon components: in relay drivers,
H-bridge motor drivers, and so on. A switched-mode power
supply also exploits this effect, but the energy is not
dissipated to heat but used for pumping additional charge
through the load.
this is the reason......
