Do resistors reduce current or voltage in an electrical circuit?
Resistors reduce the flow of current in an electrical circuit, which in turn affects the voltage across the circuit.
Does a resistor reduce current or voltage in an electrical circuit?
A resistor reduces the flow of current in an electrical circuit, which in turn affects the voltage across the resistor.
How does a resistor limit current or voltage in an electrical circuit?
A resistor limits current in an electrical circuit by impeding the flow of electrons, which reduces the amount of current passing through it. This, in turn, helps regulate the voltage in the circuit by creating a drop in voltage across the resistor.
What purpose of switch in electric circuit?
A switch in an electric circuit is used to control the flow of electricity. It can be opened to interrupt the flow or closed to allow electricity to pass through. Switches are commonly used to turn devices on or off in electrical systems.
Can electrical current exert a magnetic force?
Yes, electrical current can create a magnetic field around it, which in turn exerts a magnetic force on other magnetic objects or conductors nearby. This is known as electromagnetism, where the flow of electric charges (current) produces a magnetic field.

Resistors reduce the flow of current in an electrical circuit, which in turn affects the voltage across the circuit.

Why Cable gets heated when current flows more than its rated current why?
Because if the rated current is lower than the actual current, it causes resistance to the electrical flow which in turn is dispelled as heat.

Why is a light bulb not on when a switch is not closed?
A closed switch completes the electrical circuit, allowing current to flow through the light bulb and generate light. If the switch is not closed, there is an open circuit, meaning the current cannot flow and the light bulb does not turn on.
What is the best conducter of an electro magnet?
The best conductor for an electromagnet is usually copper due to its high electrical conductivity. Copper allows for efficient flow of electrical current, which in turn generates a strong magnetic field.
What are you doing to the electrical circuit in your radio when you turn the radio off and on?
When you turn your radio on and off, you are simply flicking the switch in the circuit, the same as any circuit with a switch in it. When you turn it on, the switch completes the circuit, and current can flow around the circuit.

What Allows electric current to flow though them to devises and components?
Switches either allow the current to flow or turn it off
Why does room light turn on at once as the switch is close?
When the switch is closed, it completes the electrical circuit, allowing current to flow instantly to the light fixture. This immediate flow of electricity energizes the light bulb, causing it to illuminate right away. The speed of electrical current is nearly instantaneous, resulting in the light turning on almost immediately after the switch is activated.
