What happens to resistance as the wire gets thicker?

What happens to resistance as the wire gets thicker?

The longer a wire is the more resistance it has due to the longer path the electrons have to flow along to get from one end to the other. The larger the cross sectional area, the lower the resistance since the electrons have a larger area to flow through. This will continue to apply no matter how thick the wire is.

What is the function of load resistance?

Load resistors are used for impedance matching, maximum power transfer, to improve output stability and to ensure a minimum of current flow. in switching power supplies, they are essential for the proper operation of the psu.

How can I change the resistance of a circuit?

Changing the resistance If you increase the number of lamps in a series circuit, there will be less current. The lamps resist the current, so if you put more lamps into the circuit, there is more resistance. You could do the same with a variable resistor.

How do you increase current in a circuit?

The two main ways of increasing the current in an electrical circuit are by increasing the voltage or by decreasing the resistance. If you increase the voltage across a component, there will be more current in the component.

Why is there more resistance in a series circuit?

If you increase the number of lamps in a series circuit, there will be less current. The lamps resist the current, so if you put more lamps into the circuit, there is more resistance. You could do the same with a variable resistor. The quantities voltage, current and resistance are linked by the relationship:

How does resistance decrease in a parallel circuit?

Example: A 2 Ω resistor is placed in series with a 6 Ω resistor. What is the total resistance? In a parallel circuit, the net resistance decreases as more components are added, because there are more paths for the current to pass through.
