Just need the answer to question 4 thanks

QA.1
a)
b)
c)
d)
A passive R-L load is supplied from a step-down DC-DC
converter (chopper) from a LiPo battery of 12 V. The chopper
operates with switching frequency of 4 kHz. The load
resistance and inductance are 10 and 50 mH, respectively,
so that the converter operates in the continuous conduction
mode. The switching components can be considered as
ideal.
Determine the required duty cycle and chopper on-time if the
chopper output average voltage is 8 V.
Calculate the average load current and the power delivered
to the load for the case considered in part a).
After certain time the battery has discharged, and the battery
voltage dropped to 10.2 V. Calculate the new values of duty
cycle and chopper on-time needed to maintain the same
voltage on the output.
How much power is now taken from the battery?
