1) A generator has a teminal voltage of 110 V when it delivers 11.4 A, and 93 V when it delivers 35.6 A.
calculate the emf. answer in units of V.
Thank you!

2) Calculate the internal resistance. answer in unit of ohm

In the first example the resistance is 9.649122 etc ohms.
R= V/I (where I is current)
In the second example 2.61 ohms again R = V/I
So the voltage drops when the load is increased. The EMF simply drops by 17 Volts as the load is increased.
Weird question. I'm assuming the load is a resistance and of course a generator produces DC - an alternator produces AC.

2 simultaneous equations
emf - 11.4 A*R = 110V
emf - 35.6 A*R = 93V
