What Resistance Is
What Resistance Is
The resistance of a component in a circuit is its ability to reduce the current flow. It is measured in ohms.
If someone resists something, which of these options best describes their actions?
What do we call the flow of electrons through a circuit?
Do you think resistance will increase or decrease the current around a circuit?
Which of the following do you think provide resistance in a circuit?
You can select multiple answers
When we talk about resistance in an electric circuit, we mean the resistance the current feels when passing through a component. It is a measure of how much a component decreases the current as it passes through it. All components provide different amounts of resistance.
Which of the following components do you think have the highest resistance to current?
Most components want to allow current to flow through them, but they can't avoid introducing a little bit of resistance. Other components, such as resistors, actually want to reduce the current in a circuit, so they have really high resistance.
Which of the following do we measure resistance in?
If an object has a high resistance, the current that flows through it will ___________.
Resistance is measured in ohms . It has a direct effect on the current flowing through the circuit. The higher the resistance, the lower the current that flows through a component.
