Question

state the effects on output volatege if dutey cycle of PMW is changed​

Answer 1

Explanation:

If you want the motor to go faster, you can drive the PWM output to a higher duty cycle. The higher the frequency of high pulses, the higher the average voltage and the faster the fan motor will spin. At this point, your duty cycle is still 50%, but you have increased the number of cycles per second to two.

Answer 2

Explanation:

Ohm's Law is a formula used to calculate the relationship between voltage, current and resistance in an electrical circuit. To students of electronics, Ohm's Law (E = IR) is as fundamentally important as Einstein's Relativity equation (E = mc²) is to physicists. E = I x R
