Two simple circuit diagrams, each with a battery, resistor, and ammeter. The left diagram shows the ammeter before the resistor; the right diagram shows it after the resistor.

Diagram showing two resistor configurations: on the left, resistors R1 and R2 are connected in series between points a and b; on the right, resistors R1 and R2 are connected in parallel between points c and d.

A diagram showing the relationships among resistor, capacitor, inductor, and memristor, with circuit symbols, equations, and arrows connecting voltage, current, charge, and magnetic flux variables.
