Question

You have a nightlight plugged into an outlet in the hallway, which uses 3.5 watts when plugged in. If the house circuit provides 120.0 volts, what is the current through this bulb?

Answer 1

Is this a physics question?

Answer 2

if it is there should b an equation for that

Answer 3

i think so idk the equation tho

Answer 4

one sec ill help u

Answer 5

ok

Answer 6

do uk how to find resistence?

Answer 7

no

Answer 8

I think what you have to do is divide watts by volts
so 3.5/120=0.029166666

Answer 9

check if that is right

Answer 10

yeah its right do uk this A circuit is used in which process?Select one of the options below as your answer:A. electricityB. magnetismC. velocityD. gravity

Answer 11

its electricity

Answer 12

dang ur good what about thisIn the process of electricity, what flows through the wires?Select one of the options below as your answer:A. protonsB. neutronsC. electronsD. positrons

Answer 13

electrons?

Answer 14

can u help me with the rest of my questions i have to answer

Answer 15

ok

Answer 16

How much current is in a circuit that includes a 9.0-volt battery and a bulb with a resistance of 4.0 ohms?Select one of the options below as your answer:A. 0.44 ampsB. 36 ampsC. 2.3 ampsD. 13 amps

Answer 17

Its C.2.3 because the equation for current is I=V/R
where I=current, V=voltage, and R=resistance
I=9.0/4.0=2.25

Answer 18

What is the voltage in a circuit that has a current of 10.0 amps and a resistance of 28.5 ohms?Select one of the options below as your answer:A. 2.85 voltsB. 285 voltsC. 0.35 voltsD. 18.5 volts

Answer 19

Using the equation that i provided you just plug in the number for the corresponding variable and solve for V

Answer 20

V=I*R
V=10.0*28.5
V=285Volts

Answer 21

i literally just got the answer when u gave it to me haha

Answer 22

Nice u got it

Answer 23

What type of relationship exists between the length of a wire and the resistance, if all other factors remain the same? Select one of the options below as your answer:A. Resistance is directly related to length.B. Resistance is directly related to the square of the length.C. Resistance is inversely related to the length.D. Resistance is inversely related to the square of the length.

Answer 24

I think its A. Resistance is directly related to length. but im not sure

Answer 25

what does it mean by square of the length?

Answer 26

idk i answered it n it was correct

Answer 27

In which situation will the lowest resistance occur?Select one of the options below as your answer:A. thick wire and high temperatureB. thin wire and high temperatureC. thick wire and cold temperatureD. thin wire and low temperature

Answer 28

Try Thick wire and high Temperature just because it seems logical

Answer 29

What does the abbreviation DC stand for in physics?Select one of the options below as your answer:A. direct chargeB. dark circuitC. direct currentD. drop charge

Answer 30

Direct Current

Answer 31

Which is true regarding AC current?Select one of the options below as your answer:A. The electrons move back and forth.B. The +/- polarity is constant.C. It is common in portable devices.D. It can only produce low voltages.

Answer 32

I think its A. The electrons move back and forth but i have to double check that

Answer 33

Think about the electricity sent to your home from a power plant. How does the voltage of the electricity that leaves the plant compare to the voltage of the electricity as it enters your home? Select one of the options below as your answer:A. low voltage to high voltageB. low voltage to low voltageC. high voltage to low voltageD. high voltage to high voltage

Answer 34

High Voltage to Low Voltage due to resistance

Answer 35

A battery is the power source for what type of current?Select one of the options below as your answer:A. ACB. BCC. DCD. all types of current

Answer 36

D. All types of current

Answer 37

Answer 43

whatever u sending i cant see the picture

Answer 44

oh ok now i got it to work, for the previous one the answer should have been A. They all contain Switches

Answer 45

Which component is used to measure the current in a circuit?Select one of the options below as your answer:A. switchB. resistorC. ammeterD. voltmeter

Answer 46

w8 dude did u answer the symbol question yet?

Answer 47

cuz the answer to that one was C.

Answer 48

yeah i already answered it its all good tho i can miss a few

Answer 49

k the answer to this one is C. Ammeter
