Operational amplifiers are fundamental electrical elements that are often used in instrumentation and control.  And, by the way, they are usually called "op-amps",

• Why learn about op-amps?
• They are widely used in instrumentation and control.
• What should you know to learn about op-amps?
• You need to know basic EE concepts about voltage & current, resistors and capacitors.
• You need ot know basic EE laws like KVL and KCL.
• What do you need to know about op-amps?
• Basic op-amp concepts
• Op-amp inverters
• Other basic circuits
• How do you use op-amps?
• You will need to be able to use op-amps for
• Instrumentation
• Control
• What if?
• If things go badly, you might need to check out the practical considerations of using op-amps.
