What are the conditions for current to flow?

In order for a current to flow, the circuit must be closed; in other words, there must be an uninterrupted path from the power source, through the circuit, then back to the power source. Voltage is sometimes called electric potential and is measured in volts.

What are the 3 effects of current flow?

When an electric current flows in a circuit it can have one or more of the following three effects: heating, magnetic or chemical.

What are the three conditions necessary for the uninterrupted flow of electric current?

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 are the two conditions for the flow of electric current in a circuit?

Explanation: The metal or wire chosen should be a conductor. 2) There should be free electrons. 3) There should be a magnetic or electric field applied on the wire or conductor.

What two conditions can cause the current flow in a circuit to be too high?

If it is normal, current will be high if resistance is low, or current will be low if resistance is high. If voltage is too high, current will be high. Current is affected by either voltage or resistance. If the voltage is high or the resistance is low, current will be high.

What are the 4 effects of current?

Name four different effects of electric current?

• Magnetic effect.
• Chemical effect.
• Heating effect.
• Electric shocks.

What are the 5 effects of electric current?

The main effects are heating, chemical and magnetic effects.

• Heating effect. When the flow of current is ‘resisted’ generally heat is produced. is is because the electrons while moving in the wire or resistor su er resistance.
• Chemical effect.
• Magnetic effect of Electricity.

What are the three elements of electricity?

Three elements are basic to all circuits:

• Voltage source (such as a battery or gen- erator). A device that supplies the energy.
• Load (such as a resistor, motor, or. lamp). A device that uses energy from. the voltage source.
• Conductive pathway (such as an insu-

What are the 2 requirements of a circuit?

There must be a closed conducting loop from the positive to the negative terminal in order to establish a circuit and to have a current.

What are the basic requirements for the flow of electric current Class 6?

Electric current flows only if there is an unbroken path or closed circuit starting from one terminal of the source, through the torch bulb, to the other terminal of the source.

In which conditions we say that the current does not flows in the circuit?

Answer: it can’t flow if its not a closed circuit . An open circuit will not flowing electric current .

What are the three basic conditions for the flow of current?

Three basic conditions are there for the flow of electric current. The loop where current passes must be closed. There must be some potential difference in the circuit. The medium through which current flows should be conductor (but at higher temp. current flows through semiconductor).

What is the meaning of current flow?

Current Flow. Current flow basically means the flow of electric charges with respect to time. In an electric circuit, when the electric charge is flowing in one direction, the current will flow in the opposite direction.

What are the conditions for a circuit to work?

The loop where current passes must be closed. There must be some potential difference in the circuit. The medium through which current flows should be conductor (but at higher temp. current flows through semiconductor). Apart from this we need power sources and in circuit some value of resistance should be present.

What are the three conditions of a closed loop circuit?

three conditions are 1, a conductor in a closed loop. 2, a source of potential in the conductor loop. 3, an electric load to balance the potential in the loop. Your instructor may have a different answer, but they are just reading the text book. there is also magnetic induced current flow to consider but is not a condition.
