How do you calculate total electric potential energy for multiple charges?
Calculate the potential energy for every unique pair of charges and then sum them up.
What is the first step to solving an electric potential energy problem?
Draw a diagram of the charge configuration.
What is the relationship between Electric Potential Energy and Electric Potential (Voltage)?
Electric Potential Energy: Energy a charge has due to its position in an electric field. | Electric Potential: Voltage; .
Compare positive and negative electric potential energy.
Positive Potential Energy: Requires work to bring like charges together. | Negative Potential Energy: Requires work to separate unlike charges.
Differentiate between positive and negative electric potential energy.
Positive: Like charges, requires work to bring together. Negative: Unlike charges, attract each other, requires work to separate.
How is electric potential energy related to electric potential (voltage)?
Electric potential energy is the energy a charge has due to its position in an electric field; related to electric potential (voltage) by .
