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.

How does current exist?

Current is the flow of electric charge, typically carried by free electrons in a conductor. When a voltage is applied across a circuit, the electrons move in response to the electric field, creating an electric current. This flow of charge allows electrical energy to be transferred and utilized in various devices.


What is the power of a ciruit with 10 ohmns 10 volts and 2 amps?

Well, first of all, if the resistance of the circuit is 10 ohms and you connect 10 volts to it,then the current is 1 Amp, not 2 . So either there's something else in your circuit thatyou're not telling us about, or else the circuit simply doesn't exist.-- If you connect some voltage to some resistance, then the resistance heats up anddissipates (voltage)2/resistancewatts of power, and the power supply has to supply it.-- If there is some current flowing through some resistance, then the resistance heats up anddissipates (current)2 x (resistance)watts of power, and the power supply has to supply it.-- If there's a circuit with some voltage connected to it and some current flowingthrough it, then the resistance of the circuit is (voltage)/(current) ohms, the partsin the circuit heat up and dissipate (voltage) x (current) watts of power, andthe power supply has to supply it.There's no such thing as "the power of a circuit". The power supply supplies thecircuit with some amount of power, the circuit either dissipates or radiates someamount of power, and the two amounts are equal.


What are the two faults which exist in a simple cell?

In a simple cell, two common faults that can occur are short circuits and open circuits. A short circuit happens when there is an unintended connection between the positive and negative terminals of the cell, causing a large current flow. An open circuit occurs when there is a break in the circuit, preventing current from flowing. Both faults can disrupt the normal functioning of the cell and may lead to decreased performance or complete failure.


Is electric current the movement of positive charged particles?

Positive charge flow is just a concept. It is just the electrons which actually exist and flow in electricity. We just assume that positive charge is flowing in direction opposite to that of electron.


Why is an earth wire connected to metalic parts of appliances?

The ground connected to metal parts ensures that no voltage potential can exist on the metal part where it could shock the user of the device. If the hot wire does touch the metal case because of some fault in the device the breaker will trip or the fuse will blow that protects the circuit.

Why can't an electric current exist if the circuit is broken?

If the electric circuit is broken, there will be no medium for transfer of electrons and flow of current. Hence, electric current does not exist.


Why electric current cannot exist if an electric circuit is broken?

Current flow is fully based on motion of electrons since there is no possibilities to motion electron in open circuit there no current flow.


Why can't electric current exist if it is broken?

Simple - we just look at the meaning of electrical current. Electrical current is the movement of billions of tiny electrons moving along a conductor, like a wire, for instance. In order to move, these electron have to be 'pushed' by a force that we call EMF or just Volts. The electrons are also 'pulled' from the other side by Volts, as well. Electrical current will not move unless it is both pulled and pushed, which requires a complete, unbroken loop of some kind of conductor. If you break that loop, called a 'circuit', then no current can flow.


What are three important characteristics of electric circuit?

Give example of pictures in electric circuit?

There are no pictures in electric circuit, only symbols, so an example does not exist.

Even without current flow there can be voltage in a circuit?

Voltage is potential energy and can exist in a open circuit.


How can you develop a magnet?

Electric current in a coil can induce magnetism in an iron nail,place near the coil.when the electric current is cut off the magnetism in the iron nail disappears.the magnetism in the nail exist so long as there is electric current in the coil.this is an electromagnet.


Can current flow in a circuit without potential difference?

A current cannot exist without voltage but voltage can exist without current.Simple example is battery. A battery has votlage even though it is not connected elsewhere.


Can an electric field exist without a magnetic field?

Yes, an electric field can exist without a magnetic field. Electric fields are produced by electric charges, while magnetic fields are produced by moving electric charges. So, in situations where there are stationary charges or no current flow, only an electric field is present.


Does electric travel outside the wire or on the in side?

Electricity typically flows inside the wire as it travels from the power source to the destination. The electrons carrying the electric current move within the conductive material of the wire, creating an electrical circuit. Electric fields may exist around the wire, but the main flow of electricity is confined to the wire itself.
