Question $1.$

Figure $1$ shows the graphical data for the discharge of one cell in a battery pack.

Figure $1$: Discharge Curve of Battery

The battery shown is discharged at a rate of $1C.$

a$)$ State the cut$-$off voltage for the battery for the given discharge rate.

Th

decimal place, in Volts is:

b$)$ State the capacity of the battery for the given discharge rate.

The capacity of the battery, to the nearest integer, in mAh is:

c$)$ After a time the open$-$circuit voltage is $3\mathrm{.}73V.$ Determine the state of charge of the battery at this time.

The state of charge of the battery, to $1$ decimal place, as a percentage is:
