The Difference between Voltage and Current

In this analogy, what does the water tower represent?

• Current

• Voltage

• Resistance

In this analogy, what does the water in the pipes respresent?

• Current

• Voltage

• Resistance

In this analogy, what component of a circuit would the pump represent?

• Current

• Voltage

• Resistance

• Battery

Resistance is an opposition to the flow of charge.

Which of the following would increase resistance to the water tower system?

• Add rocks to the pipes

• Make the pipe bigger

If the height of the water tower increases, it would have more gravitational potential energy.

In a battery, what would increase the voltage?

• For the + to become more + and the - to become more -

• To add more water.

• Increase the DIFFERENCE in charge

Answer explanation

To Increase the DIFFERENCE in charge means the same thing as making the + to become more + and the - to become more -
