By reducing the output fusing of a generator, the total output of the generator will also be reduced. The capacity of the generator will remain the same but the fault trip point will be lowered.
current flows in both directions, depending on the AC voltage, i.e when ac is higher, current flows to the dc side, and vice versa
If the load is too heavy the voltage droops because of the drop across the generator's internal impedance.
when we connected voltmeter in series it takes large current and voltage and the resistance is considerably decreases.this is why we had connected voltmeter in series combination.
the current flowing in will be low
The current, if connected to a voltage source that can supply the needed current to (R1+R2) R3, will be unchanged. If the source cannot supply the needed current, the terminal voltage will decrease, which will change the current flowing through R1 and R2.
When a capacitor is connected to a circuit, the current flow through the capacitor initially increases and then decreases as the capacitor charges up.
when excitation fails,Reactive power will be supplied by the system to which the generator is connected and generator will work as induction generator and its speed will rise a little. generator which was in over excitation mode will work in underexcitation.but there is under excitation limit which should not be reached so we should detect loss of excitation and trip generator
Nothing
this action is very dangerous and should not be considered.
Nuclear to thermal energy conversion happens inside a nuclear reactor through fission processes which produce heat. This thermal energy is then used to generate steam in a heat exchanger. The steam drives a turbine connected to an electric generator, converting the thermal energy into electrical current.
It is wise to start thinking of power in DC circuit. If a load is connected to a power source in a DC circuit, the corresponding VOLT CURRENT plot both will be in the positive quadrant. Of course, polarity must be correct. Now if the CURRENT (in the same polarity arrangement) happens to be in the negative quadrant, the power is said to be reversed. The same can be thought in an AC circuit. Taking a half wave cycle of both VOLT and CURRENT, one can apply the same understanding as in the DC circuit. If the AC circuit is capacitive or inductive, VOLT and CURRENT waves will be shifted according to the value of the capacitive or inductive load, and here one has to be aware.

When a resistor is added the current goes down, that is expressed in the equation current= voltage/ resistance
