Si unit of current is amp but they gave us power

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

you have the intensity formula wrong

SalvadorV Group TitleBest ResponseYou've already chosen the best response.1
sorry the power formula

oh so I got it wrong?
 7 months ago

SalvadorV Group TitleBest ResponseYou've already chosen the best response.1
yes, Watts=Volts*Amps Amps=Volts/Ohms

DrPepperx3 Group TitleBest ResponseYou've already chosen the best response.0
oh wait im confused .. sorry

SalvadorV Group TitleBest ResponseYou've already chosen the best response.1
watts=volts^2/ohms 2000=200^2/ohms ohms=200^2/2000 = 40 000/2000=20 ohms

don't worry, we all make mistakes

I feel stupid :l but what is ohms?
 7 months ago

ksaimouli Group TitleBest ResponseYou've already chosen the best response.0
resistance (unit)

SalvadorV Group TitleBest ResponseYou've already chosen the best response.1
ohms is the measure for resistance

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

SalvadorV Group TitleBest ResponseYou've already chosen the best response.1
see, its the same kind of question so \[0.35W=150V*amps\]
 7 months ago

SalvadorV Group TitleBest ResponseYou've already chosen the best response.1
so \[amps=\frac{ 0.35W }{ 150V }\]
 7 months ago

DrPepperx3 Group TitleBest ResponseYou've already chosen the best response.0
I was just about to put that lol
 7 months ago

DrPepperx3 Group TitleBest ResponseYou've already chosen the best response.0
ty again :)
 7 months ago

SalvadorV Group TitleBest ResponseYou've already chosen the best response.1
and we know that \[Amps=\frac{ volts }{ ohms }, 0.00233333333=\frac{ 150V }{ Ohms }\]
 7 months ago

SalvadorV Group TitleBest ResponseYou've already chosen the best response.1
remember ohms are the unit for resistance, normally noted with the sign\[\Omega \]
 7 months ago

SalvadorV Group TitleBest ResponseYou've already chosen the best response.1
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
 7 months ago

SalvadorV Group TitleBest ResponseYou've already chosen the best response.1
so we get \[\Omega=\frac{ 150V }{ 0.00233333333Amp }\]
