    electric power (watts)=votlage*amperage, amperage=voltage/resistance so 2000W=200V*Amperage (10amp). 10amp=200V/resistance (20)

    watts=volts^2/ohms 2000=200^2/ohms ohms=200^2/2000 = 40 000/2000=20 ohms

    2.An electronic device is rated at 0.35 W when connected to 150 V. What is the resistance of this device?

    see, its the same kind of question so \[0.35W=150V*amps\]

    • 6 months ago
  29. SalvadorV Group Title

    You've already chosen the best response.

    so \[amps=\frac{ 0.35W }{ 150V }\]

    and we know that \[Amps=\frac{ volts }{ ohms }, 0.00233333333=\frac{ 150V }{ Ohms }\]

    remember ohms are the unit for resistance, normally noted with the sign\[\Omega \]

  34. SalvadorV Group Title

    here we have to substitute for ohms, so we pass them to the left side multiplying, and then we pass the 0.00233333333 dividing the voltage

    • 6 months ago
  35. SalvadorV Group Title
    Best Response
    You've already chosen the best response.
    Medals 1

    so we get \[\Omega=\frac{ 150V }{ 0.00233333333Amp }\]
