Understanding Potential Difference and Electric Fields

What is the potential difference between the parallel plates connected to the battery?

• 25 volts

• 10 volts

• 15 volts

• 20 volts

Which equation is used to calculate the separation between parallel plates with a uniform electric field?

• Electric field strength equals charge divided by distance

• Potential difference equals electric field strength times distance

• Potential difference equals charge times electric field strength

• Electric field strength equals potential difference divided by separation

What is the separation between the plates when the potential difference is 15 volts and the electric field is 1200 N/C?

• 0.0125 meters

• 0.025 meters

• 0.015 meters

• 0.010 meters

How is the unit 'volt' related to 'joule' and 'coulomb'?

• Volt is joule per coulomb

• Volt is meter per joule

• Volt is coulomb per joule

• Volt is joule per meter

What is the separation between the plates in millimeters?

• 11.5 mm

• 10.5 mm

• 12.5 mm

• 13.5 mm
