When an electrical charge flows through a resistor, some of the electrical energy is converted into heat due to the resistance of the material. This heat causes the resistor to get hot, and the temperature increase is proportional to the amount of current flowing through it and the resistance of the resistor. If too much heat is generated, the resistor may be damaged or experience a change in resistance.
What else can I help you with?
How much charge flows through the switch after the switch is closed?
The amount of charge that flows through the switch after it is closed depends on the electrical circuit and the voltage applied. The charge flow is measured in coulombs.
Does current flow through a resistor, or does it flow across a resistor?
Current flows through a resistor, not across it.
How the charge of a wire changes when the electricity current flows in the wire?
When electricity current flows through a wire, the charge of the wire does not change. The flow of electrons creates an electrical current, but the total charge of the wire remains constant.
What is the point of a resistor in an electrical circuit?
A resistor in an electrical circuit is used to control the flow of electric current and reduce the amount of voltage in the circuit. It helps regulate the amount of current that flows through the circuit and protects other components from damage due to excessive current.
How can electrical energy change into heat and kinetic energy?
Electrical energy can change into heat when it flows through a resistor, causing the resistor to heat up due to the resistance in the circuit. Electrical energy can change into kinetic energy by powering electric motors, which convert the electrical energy into mechanical energy to produce motion or perform work.

The amount of charge that flows through the switch after it is closed depends on the electrical circuit and the voltage applied. The charge flow is measured in coulombs.
Resistor get hot when an electrical current flows through it?
A: the answer lies with the power consumption of any device while operating normaly.
Does current flow through a resistor, or does it flow across a resistor?
Current flows through a resistor, not across it.
Is current is drop when it flowing through the resistor?
Current flows in loops, voltage drops across elements. With relation to current, what flows in, must flow out, so no, current is not dropped across a resistor, it flows through a resistor and voltage is dropped across the resistor.
Does voltage flow across or through a resistor?
No. If a voltage is applied across a resistor, a current flows through it.
How the charge of a wire changes when the electricity current flows in the wire?
When electricity current flows through a wire, the charge of the wire does not change. The flow of electrons creates an electrical current, but the total charge of the wire remains constant.

What is the resistance of a resistor if the potential differennce across the resistor is 9 V when current of 1 A flows through the resistor?
9 ohms
Which answer best describes the flow of electrical charge?
Electrical charge flows from an area of high voltage to an area of low voltage through a conductive medium like a wire. This flow of charge creates an electric current, which is the movement of electrons.
The total current that flows through a circuit is the same as the current that flows through each individual resistor connected in series?
True
Why does a resistor heat up when an electric current flows through it?
Current moving through a resistor causes it to heat up because of the flowing electrons bumping into the atoms in the resistor.
