What is the difference between series and parallel circut?
If two or more circuit elements are connected in series, the current must pass through each of them in turn. If two or more circuit elements are connected in parallel, that means there is a "fork in the road". In this case, part of the current will pass through one element, and part, through another one.
What flows through a circuit and causes a magnetic field?
An electric current flowing through a circuit causes a magnetic field. This is due to the movement of electric charges, usually electrons, in the circuit. The magnetic field produced is perpendicular to the direction of the current flow.
What is the effect on the direction of the compass needle when you close the circuit?
When you close the circuit, a magnetic field is produced which can deflect the compass needle. The direction of the compass needle will align with the magnetic field produced by the current flowing through the circuit.
Is current constant through a circuit?
Yes, in a closed circuit, the current is constant and flows continuously through the circuit.
What happens if current flows through 2 parallel current in the same direction?
With the possible exception of some circuits that have inductance and capacitance in parallel and are excited by a pulse or an alternating voltage, the currents in two parallel branches of a circuit are ALWAYS in the same direction.
Differentiate parallel circuit and siries circuit?
If two circuit elements (e.g., two resistors) are in series (a series circuit), the current has to pass first through one, then through the other. If they are in parallel, the current has a choice, through which of the elements it passes.
What is the iffrence between a series circuit and parallel circuit?
Series circuit: elements are connected one after the other; the current (the electrons, or other charge carriers) has to pass through each of the elements in turn. Parallel circuit: elements are connected in such a way that part of the current will pass through one circuit element, part through the other.
In a series circuit how does the current differ at different places along that circuit?
In a series circuit, current will remain the same through all elements, and the voltage drop across elements will vary. So the answer is: it doesn't.
What is the difference between series and parallel circut?

If two or more circuit elements are connected in parallel, that means there is a "fork in the road". In this case, part of the current will pass through one element, and part, through another one.

An electric current flowing through a circuit causes a magnetic field. This is due to the movement of electric charges, usually electrons, in the circuit. The magnetic field produced is perpendicular to the direction of the current flow.
How does current flow around a circuit?
current in a circuit will flow in a unidirectional manner and when it passes through a resistor in the circuit it opposes its direction
What means the direction of current flow?
Electrical current flow through a circuit is normally from negative toward positive.
What determines the actual magnitude and direction of current through voltage source?
The voltage itself will determine the direction of current (assuming there isn't another source pushing current through the source backwards); the amount of current will be determined by the thevenin equivalent resistance of the circuit connected to that source (the resistance "seen" by the source, which can be lumped into a single circuit element).
What is the effect on the direction of the compass needle when you close the circuit?
When you close the circuit, a magnetic field is produced which can deflect the compass needle. The direction of the compass needle will align with the magnetic field produced by the current flowing through the circuit.
Do electrons flow in only one direction?
Yes. Electrical current only flows in a closed circuit. If it were an open circuit, there would be no current.AnswerAn interesting question. The answer is.... not necessarily! I say this because a capacitor is an open circuit, yet it allows d.c. current to flow for a short period of time (while it charges), and it allows a.c. current to flow continuously.
Is current constant through a circuit?
Yes, in a closed circuit, the current is constant and flows continuously through the circuit.
What is your observation of the current in series circuit?
The current in a series circuit will be directly proportional to the voltage applied to the circuit, and inversely proportional to the resistance in it. Additionally, there will be one and only one path for that current, as it is a series circuit. All the current in the circuit will have to pass through each each element of the circuit. The current will all flow in one direction in a DC circuit; current is unidirectional. And will flow "back and forth" in an AC circuit, or will alternate directions, as one might expect.
