Electric potential is defined as:a. Potential energy per unit charge  b. Charge per unit voltage  c. Current per unit resistance  d. Energy per unit current

Kirchhoff’s loop rule is based on:a. Conservation of energy  b. Conservation of charge  c. Ohm’s Law  d. Conservation of momentum

What is the direction of the electric field produced by a positive point charge?a. Away from the charge  b. Toward the charge  c. Perpendicular to the charge  d. In circles around the charge

Capacitors in series combine as:a. C = C₁ + C₂ + …  b. C = C₁C₂  c. 1/C = 1/C₁ + 1/C₂  d. C = 1/C₁ + C₂
