Zig-Zag vs Rectangle Resistor Symbols: Which One's Better?

Подробнее о видео

In circuit diagrams, NEMA and IEC use different symbols for resistors: NEMA (mostly used in the US) represents a resistor with a zig-zag line, symbolizing resistance to current, while IEC (used internationally, especially in Europe) uses a simple rectangle for a cleaner, more standardized look. The zig-zag design reflects older American standards, whereas the rectangle aligns with modern international conventions for clarity and consistency.
