Identify the option that has the most appropriate sequence such that a coherent paragraph is formed:
P. It is because deer, like most of the animals that tigers normally prey on, run much faster! It simply means, another day of empty stomach for the big cats.
Q. Tigers spend most of their life searching for food.
R. If they trace the scent of deer, tigers follow the trail, chase the deer for a mile or two in the dark, and yet may not catch them.
S. For several nights, they relentlessly prowl through the forest, hunting for a trail that may lead to their prey.

Ques 49 Power Electronics

The 3-phase modulating waveforms (v_a(t),v_b(t) and v_c(t)), used in sinusoidal PWM in a Voltage Source Inverter (VSI) are
v_a(t)=0.8 sin(ωt)V
v_b(t)=0.8 sin(ωt-2π/3)V
v_c(t)=0.8 sin(ωt+2π/3)V
