Diode and Transistor Circuit Analysis and Functionality
Circuit Analysis Exercises
16. Identify the components in the diagram that allow current flow and emit light when connected.
17. Modify the following circuit so that when the switch is in position 1, the motor turns in one direction and a red LED lights up, and when the switch is in position 2, the motor turns in the opposite direction and a green LED lights up. Components provided: power source, motor, switch, red LED, green LED, and two 1000Ω resistors.
18. Observe the diagram and fill in the following

Design, Drawing, and Measurement
- Design
- The collective word for all the information that is given in order to produce or build something.
- Drawing
- A type of picture that has been drawn in order to present design information.
- Scale
- The ratio between the size of items shown on a drawing and their actual size (in reality).
- Full-Scale Drawing
- The dimensions of the drawing are the same as their real size.
- Small-Scale Drawing
- Often referred to as a general arrangement drawing.

Fluid Definition and Application
A Fluid is a substance that flows, deforms, and changes shape when subject to a force or stress. It has no fixed shape but adapts its surface to the shape of its container.
Hydraulic Systems
Hydraulic systems are utilized where large, precise forces are required. Some common applications include:
- Tablet compression machines
- Bioreactor mixing and agitation
- Autoclave door actuation in sterilization units
- Aseptic packaging
- Hydraulic presses for sample preparation
All hydraulic

M/EEG Hardware Components and Principles
1. M/EEG Basics
- EEG (Electroencephalography): Measures electrical potential (Volts) via scalp electrodes.
- MEG (Magnetoencephalography): Measures magnetic flux (Teslas) using sensors close to the scalp.
- Invasive Methods: Electrocorticography (ECoG), depth recordings.
- Quote: MEG “sees less but sees better” – David Cohen.
2. EEG Details
Signal Strength and Electrodes
- Scalp EEG: 10–100 µV (peak-to-peak).
- Dura (Brain Surface) EEG: 10–20 mV.
- Electrodes: Silver (Ag)
