Why is it that when you have a dc generator connected in series does your voltage drop as you add loads to it?

A generator supplies a fixed amount of power "(IxV)" . If it has the ability of supplying 10 amps at 12 volts: 10amps x 12volts=120 watts, as you increase the "load" your voltage has to decrease to give you your rated 120 watts. 12amps x 10 volts=120 watts
if you have motor pulling a load the more load you put the slower it will run. power=speed x torque : power=pressure(voltage) x current flow:

What happens when heavy loads are connected to an electrical generator?
If the load is too heavy the voltage droops because of the drop across the generator's internal impedance.
When are series circuits useful-?
when loads act as switches
Is electric cooker connected in series or parallel?
All residential loads are connected in parallel, so that they share the same supply voltage, which is necessary for them to develop their rated power outputs.
What happens if a fuse is connected into the neutral wire?
In North America the neutral wire is never fused. This is because of the three wire circuit that uses a common neutral. If there are two loads connected across a common neutral circuit and the neutral opens a 230 volt supply will be impressed across both loads as they are now in series with the supply. If both loads were balanced then the voltage drop across both loads would be equal. Dropping 120 volts across each load. Where the problem arises is if the two loads are not balanced and voltage drop goes higher than the manufactures recommended voltage, then the connected device could burn out.
Would a 50 ohm load and a 100 ohm load connected to a 120 volt supply have the same voltage?
If they're connected one at a time ... first one and then the other ... then each one has 120 voltsacross it while it's connected to the supply.If they're connected across the supply at the same time in parallel, then of course they have thesame voltage across them, because their ends are common.If they're connected across the supply in series, then the voltage across the 50-ohm load is 40 volts,and the voltage across the 100-ohm load is 80 volts.
What is the formula which defines the voltage drop across loads in a series circuit?
Ohm's Law says that the voltage drop is equal to the resistance of the loads times the current. It is written as V = I x R
What is the function of capacitor in an electric generator?
In an electric generator, the function of a capacitor is to provide reactive power and improve the power factor of the generator. When a generator is connected to a load, the load may have a combination of resistive, inductive, and capacitive components. Inductive loads can cause the power factor of the generator to decrease, resulting in lower efficiency and voltage regulation. By adding a capacitor in parallel with the generator, the reactive power generated by the capacitor can offset the reactive power of the inductive load, leading to improved power factor correction. This helps to enhance the efficiency of power transfer and stabilizes the voltage. The capacitor absorbs and supplies reactive power, reducing the strain on the generator and ensuring a steady and efficient supply of electrical energy.
Why a voltage is always connected in parallel?
Because Voltmeter measures potential difference BETWEEN two points so it should be connected to these two points and the only way for circuit and voltmeter to be both connected to the same 2 points is in parallel. Ampermeters measure the current THROUGH some circuit so the same current that is flowing through this circuit should flow through the ampermeter too. The only way is to let the current going through the circuit to go through the ampermeter later or before, so you have to connect ampermeter in series with your circuit. The fact that voltmeters have high resistance while ampermeters have low resistance is the side effect of the way how they are connected to reduce the error introduced by devices into measured value.
What happens to the voltage in a series circuit when more loads are added?
A: assuming a infinite current source the current will increase accordingly
Why are most industrial loads placed in parallel with the source and in series with a switch?
The loads are in series with the switch so the switch can turn them on and off. The loads are in parallel with each other so they each get the same voltage when the switch is turned on. (Kirchoff's voltage law) You would not want the loads in series with each other because they would then have half the voltage and one quarter the power that you probably intended. (Assuming consistent impedance) If you had the switch in parallel, and opened(turned off) the switch, there would still be a current along the whole circuit (except that which is in series with the switch)
What is the difference between shunt generators and series generators?
1. In Shunt generators armature current is equal to sum of field current and load current whereas in series generators field current and load current is same. 2. Shunt generators field winding has high resistance and large no of turns as compared to series generators. 3. Shunt generator field winding has thin conductor and series generator has thick.
what Type of circuit is one in which all loads are connected in one single loop?
series circuit
