Yes that is exactly right.

I =dq/dt

Current in amps equals the number of Coulombs per second or [A] ⇔ [C/s]

Is true if there is voltage in circuit there must be electrons flowing through the circuit.?

No. For electrons to flow, you need a current.


What true about current flow?

Current flow refers to the movement of electric charge, typically carried by electrons in a conductor. It is measured in amperes (A) and is driven by a voltage difference across a circuit. Current can flow in two directions: direct current (DC) flows in one direction, while alternating current (AC) periodically reverses direction. The flow of current is influenced by resistance, which impedes its movement and is measured in ohms.


Is it true in the phenomenon known as the photoelectric effect electric current will flow when light shines on certain substances?

Yes, in the photoelectric effect, when light shines on certain substances, electrons are ejected from the material, creating an electric current. This effect occurs when photons (light particles) transfer enough energy to electrons in the material to overcome the binding energy holding them in place.


The potential difference of a battery depends on having an excess number of electrons at the negative terminal and a deficient number of electrons at the positive terminal?

That is true but not very - the excess of electrons at the negative terminal is small. The important thing is that if you place a load (radio set, light bulb etc.) on the battery the electrons flow through the load and this movement is supported by energy supplied by chemical action in the battery.


Valence electrons are the electrons found on the last shell of an atom true or fase?

True

True or False. The imbalance of electrons in an atom creates a movement of electrons called the electric current?

False. The imbalance of electrons in an atom does not create electric current. Electric current is the flow of electric charge, which is the movement of electrons through a conductor. The movement of electrons in an atom due to an imbalance is known as an electric field, which can lead to the flow of electric current when a conductor is present to allow the movement of electrons.


Is true if there is voltage in circuit there must be electrons flowing through the circuit.?

No. For electrons to flow, you need a current.


Is it true a current is the movement of negative charges called electrons?

Yes, a current is the flow of electric charge, typically carried by negatively charged electrons moving through a conductor. The motion of these electrons constitutes an electric current.


Electric current is the continuous flow of atoms in a conductor. True or false?

False. Electric current is the flow of electric charge (usually carried by electrons) through a conductor, not the flow of atoms.


What Current is the flow of an electric charge.true or false?

True. Electric current is the flow of electric charge through a medium. It is typically measured in amperes (A) and represents the rate of flow of electric charge.


Is it true that electrical current flows from a state of rest to a high pressure state?

No, it is not true. An electrical current (which is a flow of electrons) can only flow from a higher pressure state (higher voltage) to a lower pressure state (lower voltage).


Is it true that the flow of charges through material is electric current?

Yes, the flow of electric charges through a material is known as electric current. This flow of charges typically involves the movement of electrons in a conductor when a voltage is applied across it.


True or false does a conductor allow electric current o flow through easily?

Conductors, most metals for example, valence electrons of the atoms can be localized with very little input of energy. Insulators, most non-metals for example on the other hand, offers high resistance to flow electrons through them. In insulators valence electrons of the atoms are tightly bound and therefore at low voltages there is no flow of electrons through them.


Is it true that In Ohms law the variable i represents the rate of flow of charge which is called impedance?

"I" represents the current which is the flow of electric charge. Impedance is the measure of the opposition to the flow of current at a given voltage usually in a.c. circuits.


Is current the moving of negative electons?

True - but the "assumed direction" is opposite to reality.
