what term describes the amount of charge that passes a point in a circuit each second?
The term that describes the amount of charge that passes a point in a circuit each second is current, measured in amperes (A).
How many electrons flow through a light bulb each second if the current through the light bulb is A?
The number of electrons flowing through a light bulb each second can be calculated using the formula I = nqf, where I is the current, n is the number of electrons, q is the charge of an electron, and f is the frequency. By rearranging the formula, we get n = I / (q*f). Substituting the values of I, the charge of an electron, and the frequency into the formula will give you the number of electrons flowing through the light bulb each second.
Is an electric current the movement of negative charges called electrons?
The force moving electrons in electricity is called resistance. The electrons move toward a path of least resistance. The current is the actual movement of the electrons in a specific direction.
In which direction will each compass point when there is a large current in the direction shown?
When there is a large current in the direction shown, each compass point will point in the same direction as the current.
What is the the energy carried by each unit of a current called?
The energy carried by each unit of a current is called electric charge or Coulombs. It represents the amount of charge passing a point in a circuit per unit time and is measured in Coulombs per second (amps).
what term describes the amount of charge that passes a point in a circuit each second?
The term that describes the amount of charge that passes a point in a circuit each second is current, measured in amperes (A).
How do electrons flow on an ac source?
With electricity from the mains, the current chages direction 50 times each second, so it is called alternating current.

Why electric current current exist if an electric circuit is broken?
well, current is the movement of free electrons so if you break a point in the wire you effectively stop the electrons from flowing as the electrons need to be touching each other in order to pass on energy or charge. The reason why if there is a gap in the circuit the electrons dont just jump it is because of resistance of air as the electrons in air are not free to flow they are not conduction electrons unlike in a metal such as copper wire.
Number of electrons flowing pass one point?
The passing charges is called, "Current", and the rate of those charges is measured in "Amperes", capitalized because the word is taken from a person's name. The common electrical units are: Electromotive Force, or EMF. Measured in Volts. Current. Measured in Amperes. Resistance. Measured in ohms.
What is the name of the unit used to measure an current?
The ampere, often abbreviated to amp or A.It measures electrical current which is denoted in Ohm's Law as "I".The unit or instrument used to measure electric is called "AMMETER"More detailThe unit is named after the French physicist André Marie Ampère.A current of 1A is equal to 1 coulomb of charge passing a point in 1 second.The ampere is the unit of current. It is approximately 6.24 × 1018 electrons passing a given point each second. See the Related Link shown below for more detail. Ampere

In electronics what is a current?
An electronic current is what occurs when electrons move in a definitive direction. Not to be confused with voltage (V).The electrons (sometimes referred to as charges) move from a region of overall negative polarity towards a region of overall positive polarity because they, themselves, are negatively charged.Opposite polarities attract just like the north and south of a magnet.Electrons (charges) can only move through a conductor if a potential difference has been created between the two 'poles' of the conductor.If there is a difference (more electrons at point A in a circuit than at point B) then the conductor is said to be holding a charge.Any circuit that is storing a charge has the 'potential' to create a current. A current will flow when the electrons are allowed to travel from point A to point B.Example:When a battery is connected in series with a lamp the electrons travel from the negative terminal on the battery, along the conductor, through the lamp (causing it to illuminate, and back through the other conductor to the positive terminal of the battery.The bulb will remain lit until there is an even distribution of electrons in each pole of the battery (assuming that the circuit is not severed).When the electrons are evenly distributed at each end of the battery then the battery is said to have lost it's charge. When the battery has lost its charge the current will stop flowing.Current is measured in Amperes (Amps) and has the symbol I. {simple enough}Charge (Q) is measured in culombs. The symbol C . {a little confusing but true}The quantity (Q) of charge carried by roughly 6 million, million, million electrons is named 1 culomb and has the cymbol C. {makes above less confusing}If this many electrons (1 culomb) pass each point in a circuit every second then the current at that point is 1 Ampere.formula:1A = 1C/sQ is a symbol used to describe a number of culombs e.gif 2C pass in 1 second the current is:2 C/s = 2AIn general if Q coulombs pass in t seconds, then the current I is given as:Q = It or I=Q/t.
