  • Gain
    Find the gain whenever the output power is 18x the input power.
  • Decibel
    A circuit has an input power of 73 mW. Its output power is 18 mW. What is the loss in decibels?
  • Resistors
    Two parallel resistors connected in series give the resulting resistance $R1Ω and $R2Ω. Determine the resistance of these resistors.
  • Wiring
    The conduit has a cross-section 54² mm. Maybe put it into 6 conductors with a cross section S2 $mm²?
  • Electronics: Resistors in parallel
    Concerning calculating the resistance of the parallel combination of resistors: (1)/(R) = (1)/(R1) + (1)/(R2) Calculate the R, if R1 = 17Ω a R2 = 20Ω
