Understanding Resistors through Straw Analogy

What does the time taken to exhale through a straw represent in terms of resistance?

• The amount of air exhaled

• The diameter of the straw

• The level of resistance

• The length of the straw

How does connecting two straws end-to-end affect resistance?

• It decreases resistance

• It has no effect on resistance

• It increases resistance

• It doubles the resistance

What happens to the resistance when three straws are connected in series?

• Resistance decreases

• Resistance is halved

• Resistance increases

• Resistance remains the same

How does connecting two straws side-by-side affect resistance?

• It triples the resistance

• It has no effect on resistance

• It decreases resistance

• It increases resistance

What is the effect of adding more straws in parallel on resistance?

• Resistance remains constant

• Resistance doubles

• Resistance decreases

• Resistance increases
