An electrical current will always flow?
yes
What is the direction of current flow in a Battery and why?
Current means flow. Electric current means flow of electric charges Now there are two kind of charges. They are positive and negative But current is defined as the flow of positive charges But in metallic wires there is no chance for positive charges to flow through. Only loosely bound electrons with negative charge are capable of flowing. So current is case of metallic wire is due to electrons. So we have to assign as "conventional current". Conventional current is always opposite to the flow of electron flow Now from a battery current (conventional) flows right from positive polarity to the negative polarity. But within batter is has to flow right from negative to positive so as to complete the circuit of flow.
What is the difference between currant and current?
The spelling "currant" is a dried grape (similar to raisins). The spelling "current" can be a noun (the flow of electrical energy) or an adjective (present, up-to-date).
Steady flow of electrons?
elelctric current
What does AC and DC stand for in the electrical field?
Alternating Current and Direct Current. Electricity is voltage and current. Voltage is electrical pressure, and current is the flow of charged particles. The difference between alternating current (AC) and direct current (DC) is that the electrons in an AC circuit regularly reverse their direction. In a DC circuit electrons always flow in the same direction.
What effects magnets?
Current flow or the change of charge in time.
An electrical current will always flow?
yes
What produces magnetic effects?
Current flow or the change of charge in time.
When there is a difference in voltage the flow of charge is called?
flow of charge is called current. but the direction of flow of current is always taken oppsite to the flow of charge.
What refers to electric current when electrons always flow in the same direction in the wire?
When electrons always flow in the same direction in the wire it is known a DC (direct current).
How will you describe the graph of resistance against current?
If resistance is high that time the current flow is low. Bcoz current always flow through the low resistance path.
What does the flow of electrons make?
The flow of electricity, which is a current of electrons, or simply electron flow, creates a magnetic field around its path of travel. This is a fundamental property of charged particles. Magnetic fields are always present in the vicinity of moving charges, and moving charges always create magnetic fields. One of the four fundamental forces we know in nature is the electromagnetic force. And this is probably one of the best examples of the inseparability of current flow and a magnetic field.
Is the direction of current through a battery always from negative to positive on the terminals?
Conventional current flow is from positive to negative. Electron flow is from negative to positive
What condition are necessary for a current to be present in a circuit?
The only two things needed for current flow are electromotive force or voltage and a conductor. The amount of current flow will depend on the "Resistance" in the circuit.
Why does a switch make a light turn on and off?
The purpose of a switch is to stop and start a current flow in a circuit. The stopping of a current flow in a circuit effects the load of the circuit by stopping its action. Resuming the current flow in a circuit also resumes the action of the load.
What are the main effects produced by the flow of current in an electrical circuit?
There are three effects produced by an electric current:heating effectmagnetic effectchemical effect
What would happen if they was no resistance?
current would go to a maximum, (if there was voltage present), if there was no voltage, no current would flow. the only thing that would limit the current flow (if voltage is present) is the small resistance of the cables, but say there was no resistance it would be like in a short circuit maximum current would flow at the instant voltage is applied. that is why RCD's work as they should, you want the most amount of current to flow at once because otherwise if the current was limited it would not trip in time to stop someone getting electrocuted.
