Why does the heating effect of an electric current depends on the electrical resistance of a conductor?

The power dissipated by a resistance 'R' carrying a current 'I' is [ I2R ].
The power is dissipated as heat, and you can see from [ I2R ] that for a
given current, it's directly proportional to 'R'.

What is the path that an electrical current travels?
electric current
The current in an electrical conductor varies inversely as the resistance of the conductor The current is 2 amperes when the resistance is 960 ohms What is the current when the resistance is?
4
What is a material that will carry an electric current called?
A material that will carry an electric current is called a conductor. Conductor materials have high electrical conductivity, allowing the flow of electric charges with minimal resistance. Examples of conductors include metals such as copper, aluminum, and silver.
What is an electric conductor and insulator?
An electrical insulator is a material that resists electric current, and will not allow it to flow easily. Examples include glass and most ceramics. An electrical conductor is a material that offers very little resistance to electric current, allowing it to flow freely and easily. Most metals make excellent electrical conductors.
What is the term used for the hindrance a conductor creates to the flow of electric current?
Resistance is the hindrance a conductor creates to the flow of electric current
In an electric circuit resistance is?
Resistance is the opposition to the flow of electric current through a conductor. It is defined as the ratio of the potential difference (volts) between the ends of the conductor to the magnitude of the current (amps) through the conductor.
When current passes through a conductor what makes the conductor heat up?
The electrical resistance of the material. All materials have some electrical resistance except for superconductors.
What material allows electric current to pass through?
Electric current flows in conducting materials such as metals. The best conductor of electric current is silver, followed closely by copper and then aluminium.
Unit of electric resistance?
The unit of resistance is the 'Ohm'. A conductor through which a current of 1 ampere produces a voltage drop of 1 volt has a resistance of 1 ohm.
Created around a conductor when electrons flow through that conductor?
Then an 'electrical current' is said to be present in the conductor.
What is the flow of electric charges in a conductor?
False... That is called an electrical current.
How can a magnet be used to create an electric current?
An electrical current will flow in a conductor, when a magnet is moved next to a conductor - or when the conductor is moved next to the magnet.
