Explain the concept of bandwidth with regard to a real op-amp and how this differs from the ideal op-amp.

Ideal op-amps are considered to have infinite open loop gain at any frequency, meaning that in a feedback circuit the output voltage will always be as large as it needs to be to bring the potential differ...

If there is a parallel circuit with three branches, each branch with 3 equal LEDs (and a resistor with negligible current flow), and 100mA going through each LED, what is the current flowing from the source?

Current splits up in a parallel circuit inversely proportional to the resistance of each branch; i.e. a branch with very low resistance will get the most current whereas a branch with a comparatively high...
