How much current flows through a resistor with zero potential difference?
No current flows when the the voltage is zero.
How can the resistor be charged?
Resistors cannot be charged in the same way capacitors can, as they do not store electrical energy. Instead, resistors dissipate electrical energy as heat when current flows through them, based on Ohm's Law. When a voltage is applied across a resistor, it allows current to pass, and the resistor converts electrical energy into thermal energy according to its resistance value. Thus, while resistors are integral to circuits, they don't store charge.
What effect if any does connecting a voltmeter across a resistor in a circuit have on the current through resistor?
A very very tiny amount of the current that would normally flow through the resistor instead flows through the voltmeter, allowing it to make its measurement. For most purposes this very very tiny amount of current can be completely ignored.
How much current flows through a resistor of 285 ohms if the potential difference across the resistor is 122 volts?
Use Ohm's Law, i.e., V=IR here, V=voltage I=current R=resistance
What is the purpose of RL in the circuit?
The purpose of a resistor-inductor (RL) circuit is to manage the flow of current and voltage in an electrical system. The resistor limits the current, while the inductor stores energy in a magnetic field when current flows through it. This combination can control transient responses, filter signals, and create time delays in circuits, making RL circuits essential in applications like power supply regulation and signal processing.
Does current flow through a resistor, or does it flow across a resistor?
Current flows through a resistor, not across it.
Resistor get hot when electrical charge flows through it?
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.
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.
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.
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.
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
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.
How much current flows through a resistor with zero potential difference?
No current flows when the the voltage is zero.
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
A current of 2.0 A flows through a 20 Ω resistor What is the voltage?
40volt
How does a resistor affect the flow of electricity in a circuit: does a resistor reduce voltage or current?
A resistor affects the flow of electricity in a circuit by reducing the current that flows through it. This reduction in current leads to a decrease in voltage across the resistor.
