There are many versions of the symbol for each component in electronics. Below I’ve listed the ones I’m using the most.
Battery

Integrated Circuit
The symbol for intgrated circuits (IC) come in different forms. An IC that has a common function like a logic gate or an op-amp, usually is shown as the symbol for that function (like the schmitt-triggered inverter below). An IC that does not have a symbol for it’s function is usually shown as a box with pins and pin names (like the 555 timer below).

Other symbols and components
Note that there are more version of each of these symbols and components that are not listed here. I’ve listed the ones I use the most.
What’s the hardest part in identifying components for you? Let me know in the comment field below.

Thanks
