What else can I help you with?
What is a true of our current knowledge of electrons?
electrons from a cloud around the nucleus
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 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.
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 scientific models are based on current knowledge which can limit their effectiveness when new discoveries are made?
TRUE
Which of the following is true of our current knowledge of electrons?
Electrons are subatomic particles with a negative charge that orbit around the nucleus of an atom in specific energy levels. They play a crucial role in chemical reactions by participating in bonding between atoms. Electrons also exhibit wave-particle duality, meaning they can behave as both particles and waves.
Is current the moving of negative electons?
True - but the "assumed direction" is opposite to reality.
Is it true that current is a the rate of flow of electrons?
Yes, current is the flow of electric charge, typically carried by electrons in a conductor. It is measured in amperes and represents the rate at which electrons pass through a given point in a circuit.
Is it true that a battery produces alternating current?
No. A battery produces DC, or Direct Current.
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).
When was True Knowledge created?
True Knowledge was created in 2007.
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.
