Standardized symbols for electronic components in a circuit diagram.

A graphical representation of an electrical circuit.

Component providing electrical energy in a circuit.

The flow of electrical charges through a conductor.

Single-Pole Single-Throw switch, used to open or close a circuit.

Single-Pole Double-Throw switch, can connect to one of two circuits.

An electrical circuit where the path is complete, allowing current to flow.

A unit of electric charge representing current flow for one hour.

The total energy in a battery, calculated in kWh.

The cost of electricity given the amount consumed in kWh and its price.

The type of current commonly used in homes, typically alternating current (AC).

The measure to prevent excessive current flow in audio systems which could damage components.

The flow of charges ΔQ through a conductor in time Δt, I = ΔQ/Δt.

The SI unit for electric current is the Ampere (A).

Electric current consists of free-moving charges, which can be positive or negative.

The actual direction of charge movement; positive charges move from positive to negative.

Defined direction of current flow, always from positive to negative, like the electric field lines.

Increasing charge flow through a conductor in the same time increases the current.

If the same charges flow through a conductor in a shorter time, the current increases.

If the current is decreased, the time until a certain amount of charges flows increases.

Current can be calculated by I = ΔQ/Δt; for example, 6 μC in 3 s gives I = 2 μA.

A circuit that divides input voltage into smaller output voltages based on a ratio.

A resistor with constant resistance regardless of voltage or current changes.

A resistor whose resistance changes with applied voltage or current.

The process of quantifying the resistance of a component by applying different voltages.

The transformation of electrical energy into other forms like heat or motion.

A fundamental equation that relates voltage, current, and resistance (V=IR).

Graphs that represent the behavior of a component under different voltage and current conditions.

Determining whether a component behaves like an ohmic or nonohmic resistor based on experiments.

A device that converts electrical energy into mechanical energy.

A diode that emits light when current flows through.

A resistor with lower resistance at higher temperatures.

A resistor with higher resistance at higher temperatures.

A voltage-dependent resistor that protects circuits from voltage spikes.

Graph that plots current (I) against voltage (U) for a component.

Graph that plots resistance (R) against voltage (U) for a component.

Specific values of voltage (V) and corresponding current (I) for a circuit.
