Power and regulators

we start straight into electrical signals for power. We would have a in deep lecture specific in signal for sensors.

DC vs AC​

Voltage, Current, Resistance and Power​

Tools and Equipments​

  • Multimeter, oscilloscope, bench power supply readouts, signal generator; what each instrument measures and when to use it
  • Resolution, accuracy, precision, tolerance, calibration, systematic vs random error

Considerations​

  • Input impedance, burden voltage, probe effects, ground reference issues
  • Selecting measurement range, safe connection, checking polarity, avoiding shorts, interpreting unstable readings
  • Key rules for reliable measurement; preparation for power sources and regulators
  • Why power supply quality matters in measurement and control systems
  • Batteries, USB power, bench supplies, wall adapters, DC/DC modules; voltage and current ratings
  • Voltage regulation, current limit, internal resistance, ripple, noise, voltage drop, load changes
  • Linear regulators, switching regulators, LDOs; efficiency, heat, dropout voltage, output stability
  • Estimating current consumption; selecting supply voltage and current capacity; safety margins
  • Decoupling capacitors, grounding, reverse polarity protection, overcurrent protection, thermal issues
  • Key selection criteria for power sources and regulators; link to sensors and microcontrollers
