The terminal voltage of a series generator is 150 V when the load current is 5 A. If the load current is increased to 10 A, the terminal voltage will be

In a series generator, the terminal voltage depends on the load current. As the load current increases, the magnetic field produced by the series field winding also increases, leading to a higher induced EMF and, consequently, a higher terminal voltage.

However, in real situations, the increase in terminal voltage may not be exactly proportional to the increase in current due to factors such as armature reaction and the saturation of the magnetic core. But for a simplified analysis, we can assume that the relationship between current and terminal voltage is linear for small changes in current.

### Given:
- Initial terminal voltage, ( V_1 = 150 ext{ V} )
- Initial load current, ( I_1 = 5 ext{ A} )
- New load current, ( I_2 = 10 ext{ A} )

If we assume the generator's characteristics are linear in this range, the terminal voltage will approximately double when the current doubles because the generated EMF in a series generator is proportional to the current.

### Calculation:
Since the load current doubles from 5 A to 10 A, and assuming linear behavior, the terminal voltage should also approximately double:

[
V_2 = V_1 imes rac{I_2}{I_1} = 150 ext{ V} imes rac{10 ext{ A}}{5 ext{ A}} = 150 ext{ V} imes 2 = 300 ext{ V}
]

### Answer:
The terminal voltage will be approximately **300 V** when the load current is increased to 10 A.

It's wrong bcz V= Eg-I(Ra+Rse)
If I increase V will be decrease

No way.....ithink voltage will less than 100 volt
