B.5 - 2 - Voltage

What is voltage?

• A measurement of the electrical potential energy per unit charge between two points in an electric field.

• The total electrical energy stored in an electric field.

• The force exerted on a charge in an electric field.

• The rate at which electrical energy is consumed.

What is the standard variable and unit for voltage?

• V, Joules

• V, Volts

• E, Newtons

• Q, Coulombs

Which equation correctly defines voltage in terms of work and charge?

• V = Work * q

• V = q / Work

• V = Work / q

• V = q + Work

An electric field has a strength of 10 N/C. What is the voltage across a distance of 10 meters within this field?

• 10 V

• 50 V

• 100 V

• 200 V

What is the key difference between "Electrical Potential Energy" and "Electrical Potential"?

• Electrical Potential Energy is measured in Volts, while Electrical Potential is measured in Joules.

• Electrical Potential Energy refers to the work a field can do on a charge, while Electrical Potential refers to the work a field can do per unit charge.

• Electrical Potential Energy is a scalar, while Electrical Potential is a vector.

• Electrical Potential Energy is only for static charges, while Electrical Potential is for moving charges.
