Answer 2

The modulation index is given by the formula

• $I_{t}$ = $I_{c}$$\sqrt (1 + [\frac{m^{2} }{2} ]{} )$

Therefore when the modulation is applied and is increased to 15%

The value of $I_{t}$ = 1500  $I_{c}$

⇒              1500  = $\sqrt (1 + [\frac{m^{2} }{2} ]{} )$

    2246999        = $\sqr ( [\frac{m^{2} }{2} ]{} )$

  4499998 = ${m^{2} }$

The modulation factor is m = 2121.3
