Puzzle IDE-E-040 · v2026.3

Ten words for the basic parts of a simple electrical circuit, matching a typical first electricity classroom experiment.

The shortest words ("wire" and "bulb") help new solvers gain confidence quickly, while longer entries such as "current" and "voltage" encourage them to scan the whole grid instead of stopping after the first few finds. In total, this puzzle hides 10 words (circuit, battery, wire, switch, current, voltage, bulb, plug, energy, spark) across a 12x10 grid, using 15 of its 19 unique letters at least twice.

Why we chose this word list

Every word here corresponds to a real, physical part of the simple circuit diagrams drawn in elementary science class.

"Switch" is included because understanding how a circuit can be opened and closed is the first real electrical concept most students learn hands-on.

Puzzle IDE-M-040 · v2026.3

Fifteen words distinguishing conductors from insulators and introducing the real components used in household wiring.

The shortest words ("fuse" and "short") help new solvers gain confidence quickly, while longer entries such as "transformer" and "alternating" encourage them to scan the whole grid instead of stopping after the first few finds. In total, this puzzle hides 15 words (conductor, insulator, resistor, capacitor, transformer, generator, alternating, direct, grounding, short, amperage, wattage, fuse, socket, terminal) across a 15x15 grid, using 16 of its 19 unique letters at least twice.

Why we chose this word list

"Conductor" and "insulator" are correctly contrasted — materials that let electricity flow versus materials that block it — a foundational electrical safety concept.

"Alternating" and "direct" (current) are the two real types of electrical current, distinguishing household power from battery power.

Puzzle IDE-H-040 · v2026.3

Twenty terms from real electronics and electrical engineering — semiconductors, transistors, impedance — the vocabulary behind how modern electronics actually work.

The shortest words ("diode" and "charge") help new solvers gain confidence quickly, while longer entries such as "semiconductor" and "superconductor" encourage them to scan the whole grid instead of stopping after the first few finds. In total, this puzzle hides 20 words (induction, electrostatic, semiconductor, resistance, impedance, frequency, oscillator, rectifier, transistor, diode, circuitry, electrode, polarity, conductivity, superconductor, electrolyte, charge, discharge, amplifier, terminal) across a 20x20 grid, using 18 of its 20 unique letters at least twice.

Why we chose this word list

"Transistor", "diode" and "rectifier" are the actual building blocks of every modern electronic device — genuine component names, not generic electricity words.

"Superconductor" refers to a real, specific class of materials with zero electrical resistance at very low temperatures — precise physics, not exaggeration.
