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.

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.
The total current that flows through a circuit is the same as the current that flows through each individual resistor connected in series?
True
When a electric current flows through a wire it creates a?
When an electrical current flows through a wire it creates what is called an Electro Magnetic Field.A magnetic field is create when an electric current flows through a wire.
How much current flows through a resistor with zero potential difference?
No current flows when the the voltage is zero.
Why does the cord of an electric heater not glow while the heating element does?
The heating element of an electric heater is a "resistor", the cord which conducts the electricity is not. The resistance of the element of an electric heater is very high. As current flows through the heating element, it becomes red hot and glows. On the other hand, the resistance of the cord is low. It does not become red hot when current flows through it.
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
What is a magnet created when electric current flows through a coil of wire?
A magnet created when electric current flows through a coil of wire is called an electromagnet.
A current of 2.0 A flows through a 20 Ω resistor What is the voltage?
40volt
What flows through an electric circuit?
An electrical current.
What is a path through which electric current flows?
"circuit"
When too much current flows through a condutor it is called a?
electric current
