Does the generator at a commercial power station produce dc or ac? A battery produces direct current, which refers to the flowing of charges in one direction. A commercial power station produces alternating current, where electrons in circuit are moved first in one direction then opposite.
Does a battery produce dc or AC does the generator at a power station produce dc or AC?
14. Does a battery produce dc or ac? Does the generator at a power station produce dc or ac? The battery produces DC, and the generator at a power station produces AC.
Does the generator at a commercial power station produce dc or AC?
Does a battery produce dc or ac? Does the generator at a commercial power station produce dc or ac? The battery is dc; the generator is ac.
What condition is necessary for flow of heat?
The condition necessary for the flow of heat is temperature difference. Negative charges flow from high potential to low potential through a circuit. The condition necessary for the flow of charge is potential difference.
What is the role of a battery in an electric circuit describe a mechanical analogy?
The battery acts as a charge pump in a circuit, moving charge between terminals so as to supply an electric potential difference across the two ends of a circuit. It serves an analogous role as the water pump in a water circuit.
What produces electric current in the generator?
A basic electromagnetic generator has a series of insulated coils of wire that form a stationary cylinder—called a stator—surrounding an electromagnetic shaft—called a rotor. Turning the rotor makes an electric current flow in each section of the wire coil, which becomes a separate electric conductor.
What is different between AC and DC?
In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically.
How does a DC generator produce electricity?
In a DC generator, field coils produce an electromagnetic field and the armature conductors are rotated into the field. Thus, an electromagnetically induced emf is generated in the armature conductors. The direction of induced current is given by Fleming’s right hand rule.
Does electric charge flow across a circuit or through a circuit does voltage flow across a circuit or is it impressed across a circuit?
Charge flows through a circuit, and voltage is established across a circuit.
Does current flow across or through a circuit?
Current only flows when a circuit is complete when there are no gaps in it. In a complete circuit, the electrons flow from the negative terminal on the power source, through the connecting wires and components, such as bulbs, and back to the positive terminal.
What increases as you heat up a substance?
When a substance is heated, it gains thermal energy. Therefore, its particles move faster and its temperature rises.
What does a battery supply to a circuit?
The role of a battery (or cell) in an electric circuit is to supply energy to the circuit by doing work upon the charge to move it from the low energy terminal to the high energy terminal.
How does a battery work in a circuit?
A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The flow of electrons provides an electric current that can be used to do work.
What is the role of battery in an electric circuit?
The key functions of a battery and bulb in a circuit are explained. A battery is a source of energy which provides a push – a voltage – of energy to get the current flowing in a circuit. … When the energy in the battery is used up there is no current and the bulb does not light up.
