GIVEN :-
- An arc lamp requires a direct current of 10A at 80V to function .
- It is connected to
- A 220V (rms) .
- And 50 Hz AC supply .
TO FIND :-
- The series inductor needed for the arc lamp .
SOLUTION :-
☯︎ Resistance of lamp(By Ohm's Law) is,
- ➪ R = 80/10
- ➪ R = 8Ω
✪︎︎︎ When inductor is connected in series and source is applied,
✞︎ Where,
✞︎ Where,
= 220 V
= 10 A
= 8 Ω
= 2 π f
✞︎ Where,
= 50 Hz
The series inductor needed for the lamp is "0.065 H" .
