This is a Long Answer Type Questions as classified in NCERT Exemplar

Maximum voltage = 100/2 = 50V

And minimum voltage = 20/2 = 10V

Percentage modulation= max voltage -min voltage/ max voltage + min voltage * 100

= 50 - 10 50 + 10 * 100 = 66.67%

Peak career voltage= max voltage+ min voltage/2= 50+10/2=30V

Peak value of informati
