What causes current flow?
Current flows due to gravity. Example is the water current on a river. Wind is also another factor that causes current to flow, just like ocean water.
Why secondary terminal voltage decreases with increase in load?
An increase in load (equivalent to a decrease in resistance*) causes an increase in load current. This increases the internal voltage drop within the transformer, and the terminal voltage reduces accordingly.[*An increase in load means more current is being drawn by that load, so an increase in load is equivalent to a decrease in load resistance]
What are the differences between emf and voltage drop?
emf and voltageAnswerElectromotive force is the potential difference created by a source, such as a battery or generator, when it is not connected to a load -in other words, on 'open circuit'.Voltage drop is the potential difference across a load, such as a resistor, which causes current to flow through that load.A voltage drop occurs, internally, in batteries and generators, when they are supplying a load. The battery or generator's terminal voltage, when supplying a load, is its e.m.f. less its internal voltage drop.
How does the regulator control the output to the battery?
the regulator monitors battery or system voltage and adjusts current flow or magnetic field to the rotor. The magnetism of the rotor causes power to be generated in the stator. This supplies power to run the vehicle ands charge the battery. In other words the regulator adjusts the magnetic power required to make electricity. In operation it keeps vehicle system voltage to between 14.0 to 14.7 volts.
Does a discharging battery can cause health problems?
Not a 'discharging' battery. Depends on the type of battery. A lead acid battery gives off Hydrogen when 'charging', which could be hazardous to health, if a spark causes it to explode. A 'discharged' battery can have an impact on it's own health. Best to keep them charged.
What causes current to flow in a battery?
Current flows in a battery due to the movement of charged particles, typically electrons, from the battery's negative terminal to its positive terminal through an external circuit. This movement is driven by the potential difference, or voltage, between the terminals of the battery.
What causes current to flow from one terminal of the battery to the other?
Current flows from negative to positive. The current flows because of OHM's law. Click the link.
When wires are connected to the terminals of a battery. what causes electric current in the circuit?
The electric current in a circuit is caused by the flow of electrically charged particles, typically electrons, through the wires. When the battery is connected, it creates a potential difference (voltage) that pushes the electrons to move from the negative terminal to the positive terminal, creating a continuous flow of current in the circuit.
What causes the negative terminal on a battery to heat up?
A bad connection or heavy draw.
What causes a deposit of turquoise powder on the negative terminal of a car battery?
corrosion of copper, from battery acid vapors, most likely.
How do battery terminal anti corrosion rings work?
They absorb the sulfuric acid fumes which causes corrosion.
What causes a posite current in a battery?
A electrical from a battery is the flow of elecrons through a circuit in the opposite dirrection to the current flow. This current flow also happens inside the battery between the plates.
When the wires are connected to the terminals of the battery what causes electric current in a circuit?
The resistance of the load is what causes an electric current to flow in a circuit.
Which way does current flow in a led?
Current flows from the positive terminal (anode) to the negative terminal (cathode) in a LED (Light Emitting Diode). This flow of current causes electrons to release energy in the form of light, illuminating the LED.
How does internal resistance affect operation of a cell or battery?
It causes the battery's voltage to drop when a current is drawn from it.
What effects causes the difference in terminal voltage between the increasing and decreasing field excitation current?

Does a battery supply the electrons in an electric circuit?
Yes, a battery supplies the electrons in an electric circuit. The chemical reactions inside the battery create a flow of electrons, which then move through the circuit to power devices connected to it.
