How does current change through a resistor?
When an electric current flows through a resistor, the resistor resists the flow of the current, causing a decrease in the current. This decrease in current is proportional to the resistance of the resistor, as described by Ohm's Law.
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.
The total current that flows through a circuit is the same as the current that flows through each individual resistor connected in series?
True
How much current flows through a resistor with zero potential difference?
No current flows when the the voltage is zero.
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.
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 type of energy flows through a wire?
Electric energy flows through a wire when an electric current passes through it.
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.
A current of 2.0 A flows through a 20 Ω resistor What is the voltage?
40volt
