Question

help? 2 questions medal c:!

Answer 1

1.A 2000 W toaster operates on a household circuit of 200 V. What is the resistance of the wire the make up the heating element of the toaster?

Answer 2

Resistance = Voltage / Current

Answer 3

0.1?

Answer 4

Si unit of current is amp but they gave us power

Answer 5

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

Answer 6

20 ohms

Answer 7

\[power=\frac{ V }{ I }\]

Answer 8

solve for V

Answer 9

from above equation

Answer 10

ty :) @ksaimouli and @SalvadorV kk hold on

Answer 11

you have the intensity formula wrong

Answer 12

me?

Answer 13

sorry the power formula

Answer 14

P=V*I

Answer 15

oh so I got it wrong?

Answer 16

yes, Watts=Volts*Amps Amps=Volts/Ohms

Answer 17

oh wait im confused .-. sorry

Answer 18

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

Answer 19

don't worry, we all make mistakes

Answer 20

I feel stupid :l but what is ohms?

Answer 21

resistance (unit)

Answer 22

ohms is the measure for resistance

Answer 23

oohh ok! ty for helping me c: do you mind helping with 1 more?

Answer 24

and ksaimouli has his formula wrong .-.

Answer 25

sure

Answer 26

that's why I got confused :c and kk

Answer 27

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

Answer 28

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

Answer 29

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

Answer 30

I was just about to put that lol

Answer 31

ty again :)

Answer 32

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

Answer 33

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

Answer 34

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

Answer 35

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

Answer 36

got it ! :) so =64285.72

Answer 37

yea.

Answer 38

sorry they left u so soon.

Answer 39

um ok

Answer 40

wow. nice pic.

Answer 41

perfect! :D

Answer 42

wow dude. ur late.

Answer 43

.-. ok, whatever you say

Answer 44

I'm actually trying to help people here instead of flirting you know?

Answer 45

i'm helping finish the work u left unfinished. plus i could get her before u do anyway.

Answer 46

I don't care about that, I have a girlfriend, plus just hopping in and saying "yes" is not exactly helping much

Answer 47

i know. but i also know not 2 leave a girl hanging.
