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.
Which of the following is true of our current knowledge of electrons?
they are negitivly charged electrons are outside the nucleus
Is it true in the phenomenon known as the photoelectric effect electric current will flow when light shines on certain substances?
Yes, it is true. See the link bellow.
Valence electrons are the electrons found on the last shell of an atom true or fase?
True
How can an AND gate be replaced by series switches?
An AND GATE has two inputs that must both be true for the output to be true. If you have two switches in series then they must both be closed for current to flow. This is analogous to having two true signals on the input of an AND GATE.
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.
''Ohm's law is the tendency for material to oppose the flow of electrons''is this true?
No, resistance is the tendency to oppose the flow of electrons. Ohm's Law simply relates resistance, voltage, and 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).
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.
True or False. The imbalance of electrons in an atom creates a movement of electrons called the electric current?
true
What is a true of our current knowledge of electrons?
electrons from a cloud around the nucleus
What is true of our current knowledge of electrons?
electrons from a cloud around the nucleus
Insulator stop the flow of electrons truue or false?
True.
Which of the following is true of our current knowledge of electrons?
they are negitivly charged electrons are outside the nucleus
Is conventional flow or electronic flow true?
Electronic flow is true. Conventional flow was thought to have positive charges flowing from the + terminal to the - terminal. This was before we knew that it is actually the electrons which flow, and the positive charges cannot move out of their atomic nuclei. Now that electrons have been detected, and protons are known to stay within the nucleus unless a nuclear reaction takes place, we know that it is the electrons that flow from the - terminal to the + terminal. This is known as electronic flow.
Is it true that when an electric current flows through a long conductor each free electron moves through a relatively short distance?
It is not true that when electric current flows through a long conductor each electron moves through a relative short distance because electric current is the continues flow of electrons.
