# Current of Electricity: electrons

• balibone
In summary, electricity is the movement of electrons through a conductor, which creates a current that can power devices and systems. This flow is caused by a potential difference or voltage between two points, with electrons moving from the negative to the positive terminal. They serve as primary carriers of electric current and move in a continuous loop in a circuit. The flow of electrons can be influenced by factors such as resistance, voltage, and temperature.

## Homework Statement

A wire carries a current of 2.0 A for 1.0 hour. How many electrons pass a point in the wire in this time?
A
1.2 x 10-15
B
7.2 x 103
C
1.3 x 1019
D
4.5 x 1022

Q=I/t

## The Attempt at a Solution

Q=2(60)=120
number of electrons= 120/1.60217733 × 10-19= but the answer isn't any of the options..ok i realized my super careless mistake (1hr=60s)

Is it correct?

## 1. What is electricity?

Electricity is the flow of electrons through a conductor, creating a current that can power various devices and systems.

## 2. How does electricity flow?

Electricity flows when electrons are able to move freely through a conductive material, such as a wire. This movement is caused by a potential difference or voltage between two points, which creates a flow of electrons from the negative to the positive terminal.

## 3. What is the role of electrons in electricity?

Electrons are the primary carriers of electric current. They have a negative charge and are attracted to the positive terminal of a power source, creating a flow of electricity.

## 4. How do electrons move in a circuit?

Electrons move in a circuit in a continuous loop, from the negative terminal of a power source through the circuit and back to the positive terminal. This movement is driven by the potential difference between the two terminals.

## 5. What factors affect the flow of electrons in a circuit?

The flow of electrons in a circuit can be affected by the resistance of the material, the voltage of the power source, and the temperature of the conductive material. Changes in any of these factors can impact the overall flow of electricity in a circuit.
