Understanding Voltage in Physics

What does voltage measure in an electric field?

• The magnetic force

• The speed of electrons

• The electrical potential energy per unit charge

• The resistance of the field

How is voltage related to work and charge?

• Voltage is the product of work and charge

• Voltage is the sum of work and charge

• Voltage is the ratio of work to charge

• Voltage is the difference between work and charge

In the example with a 2-coulomb charge, what was the calculated voltage across 10 meters?

• 50 volts

• 200 volts

• 500 volts

• 100 volts

What happens to the voltage when a different charge is used in the same electric field?

• The voltage increases

• The voltage decreases

• The voltage remains constant

• The voltage becomes zero

How does the distance affect the voltage in an electric field?

• Voltage decreases with distance

• Voltage depends on the distance traveled

• Voltage increases with distance

• Voltage is independent of distance

What is the relationship between electric field, distance, and voltage?

• Voltage is the ratio of electric field to distance

• Voltage is the product of electric field and distance

• Voltage is the sum of electric field and distance

• Voltage is the difference between electric field and distance

What is another term for electrical potential?

• Potential difference

• Magnetic potential

• Potential energy

• Electric current

How is electrical potential energy different from electrical potential?

• They are the same

• Electrical potential energy is per unit charge, while electrical potential is total energy

• Electrical potential energy is measured in volts, while electrical potential is in joules

• Electrical potential energy is total energy, while electrical potential is per unit charge

What unit is used to measure electrical potential?

• Volts

• Coulombs

• Joules

• Newtons

What does electrical potential energy refer to?

• The speed of charge movement

• The total work a field can do on a charge

• The work done per unit charge

• The resistance in a circuit
