MCQ
A solenoid is at potential difference $60\, V$ and current flows through it is $15$ ampere, then the resistance of coil will be ............ $\Omega$
- ✓$4$
- B$8$
- C$0.25$
- D$2$
✓
Answer
Correct option: A.
$4$
a
(a) ${\rm{Resistance}} = \frac{{{\rm{Potential}}\;{\rm{difference}}}}{{{\rm{Current}}}}$
(a) ${\rm{Resistance}} = \frac{{{\rm{Potential}}\;{\rm{difference}}}}{{{\rm{Current}}}}$
