In any electrical conductor which is not a superconductor, there is some degree of resistance. In the process of overcoming that resistance, the moving electrons will disturb the various atoms that they pass by, and therefore will increase their vibration, which on a larger scale is seen as heat.

What do you mean by magnetic affect of electric?
The magnetic effect of electric current is known as electromagnetic effect. It is observed that when a compass is brought near a current carrying conductor the needle of compass gets deflected because of flow of electricity. This shows that electric current produces a magnetic effect.
What is an electric current flow diagram?
An electric current flow diagram is a visual representation that shows the direction of electric current within a circuit. It typically uses arrows to indicate the flow of electrons from the negative terminal of the power source to the positive terminal. The diagram helps in understanding how electricity moves through a circuit.
How can an electric current produce a magnetic field and what is the relationship between the two phenomena?
An electric current produces a magnetic field because moving electric charges create a magnetic field around them. This relationship is described by the right-hand rule, which shows the direction of the magnetic field around a current-carrying wire. The magnetic field and electric current are interconnected through electromagnetism, as discovered by physicist Hans Christian Oersted in 1820.
What is a galvnometer?
A galvanometer is a device that measures electric current by deflecting a pointer on a scale. It works based on the principle of electromagnetic induction. Galvanometers are often used in scientific instruments and electrical equipment to detect and measure small amounts of current.
What size breaker do you use for a furnace?
It depends on the rating of the furnace. There should be a plate or sticker somewhere on the furnace that shows the rating. If you are just powering a blower motor the rating will be lower than if you have an electric heating element.
What does current mean in science?
It is probably used in the sense that current electricity is the opposite of static electricity. Current is a measure of the movement of electric charges, while in static electricity the charges do not move much.
What happens to power dissipation of value of electric current passing through a conductor of constant resistance is doubled?
Power dissipation in a conductor is given by the formula ( P = I^2 R ), where ( P ) is power, ( I ) is the electric current, and ( R ) is the resistance. If the electric current is doubled, the new current becomes ( 2I ). Substituting this into the power formula results in ( P' = (2I)^2 R = 4I^2 R ), which shows that the power dissipation increases by a factor of four. Therefore, doubling the current through a constant resistance results in a fourfold increase in power dissipation.
What equation do you use to calculate charge?
The equation used to calculate electric charge (Q) is ( Q = I \times t ), where ( I ) is the current in amperes and ( t ) is the time in seconds during which the current flows. Charge is measured in coulombs (C). This relationship shows that charge is the product of current and the duration of its flow.
Function block diagram of the digital multimeter?
A digital multi meter is what is used to find electric current. A block diagram shows all of the working parts of the multi meter and how they are connected.
What is a thermostix 2000?
Thermostix 2000 is a two-compound cement existing of powder and liquid. It has excellent electric resistance and it shows excellent results as insulation or heating elements. The connection is waterproof and resistant to most aciditys and hot conditions.
What is the relationship between power, current, and voltage in an electrical circuit?
In an electrical circuit, power is the product of current (the flow of electric charge) and voltage (the force that drives the current). The relationship between power, current, and voltage is described by the equation P I x V, where P is power, I is current, and V is voltage. This equation shows that power increases when either current or voltage increases in a circuit.
Which statement shows liabilities?
Balance sheet is the financial statement which shows all the current as well as non-current liabilities of business.
