A Resistor restricts the flow of current.
What is a resistor in a circuit for dummies?
A small component that provides a specific amount of resistance in an electronic circuit is called a Resistor. Resistive elements are an essential part of nearly every electronic circuit.
Why is a resistor needed in a circuit?
The materials used to make the Resistors make it difficult for the electrical charges to flow through a circuit.
How does a resistor affect a circuit?
The current before and after the narrow pipe is the same.
Does resistor reduce voltage or current?
“R” is the constant of proportionality and tells how much it varies. Ohm’s law states that if a current is flowing through a resistor, there will be a voltage dropped across it.
