What conditions are needed for charge to flow?

What conditions are needed for charge to flow?

We need two things for an electric current to flow:

• something to transfer energy to the electrons, such as a battery or power pack.
• a complete path for the electrons to flow through (an electric circuit )

What condition is necessary for the flow of heat What Analogus condition is necessary for the flow of charge?

Temperature difference is a necessary condition for the flow of heat. Similarly, a voltage difference is necessary for the flow of charge.

What condition is necessary for a sustained flow of current electricity?

What condition is necessary for a sustained flow of electric charge through a conducting medium? a sustained electric current requires a suitable pumping device to maintain a difference in electric potential–to maintain a voltage.

What are the two things required for electricity to flow?

First there must be a circuit (an unbroken path through which electricity can flow) Second the circuit must have a power source that causes the electrons to start moving. an unbroken path through which electricity can flow.

What are the 3 requirements of a circuit?

Every circuit is comprised of three major components:

• a conductive “path,” such as wire, or printed etches on a circuit board;
• a “source” of electrical power, such as a battery or household wall outlet, and,
• a “load” that needs electrical power to operate, such as a lamp.

What are the main conditions necessary for the flow of heat?

(i) The two objects should be in direct contact with each other. (ii) The temperature of the two objects should be different. Heat will flow from a hotter object to a cooler object.

What is the error in saying the source of electrons?

What is the error in saying the source of electrons in a circuit is the battery or generator? The source of the electrons in a circuit is the conducting material in a circuit not the battery. From where do the electrons originate that produce an electric shock when you touch a charged conductor?

What 3 things does a circuit need for current to flow?

To produce an electric current, three things are needed: a supply of electric charges (electrons) which are free to flow, some form of push to move the charges through the circuit and a pathway to carry the charges. The pathway to carry the charges is usually a copper wire.

What causes electricity to flow?

Atoms are made up of protons, neutrons, and electrons. Electricity is created when an outside force causes electrons to move from atom to atom. The flow of electrons is called an “electrical current.” Voltage is the “outside force” that causes electrons to move.

What is needed for a circuit?

Minimum components needed for an electrical circuit are a power supply, a load suited to the power supply, and wiring as a conductor. A switch controls current flow into a circuit.

Why does light generate heat?

When visible light is absorbed by an object, the object converts the short wavelength light into long wavelength heat. This causes the object to get warmer. Sunlight passes through the glass and it is absorbed by the plants and other objects in the greenhouse.

Which material does not conduct heat?

insulators
Feather, fur, and natural fibers are all examples of natural insulators. These are materials that allow birds, mammals and human beings to stay warm. Thus, the materials which do not conduct heat are called insulators.

When does charge flow from one end to the other?

Likewise, when the ends of electric conductors are at different electric potentials, charge will flow from one end to the other. WITHOUT a potential difference NO CHARGE WILL FLOW 2. What condition is necessary for the sustained flow of water in a pipe? What analogous condition is necessary for the sustained flow of charge in a wire?

What is an analogous condition for the sustained flow of charge in a wire?

What analogous condition is necessary for the sustained flow of charge in a wire? Likewise, to attain a sustained flow of charge in a wire some arrangement must be made to maintain a difference potential in the wire while charge flows from one end to the other continuously. Nice work!

Which is necessary for the flow of heat?

1. What condition is necessary for the flow of heat? What analogous condition is necessary for the flow of charge? a). When conducting materials are at different temperatures, there is a difference potential present, and heat will flow from hot to cold. b).
