What is the resistance of a toaster that uses 2A when connected to a 120V power source?

60 ohms

Explanation:

From Ohm's Law:

V = IR

Where V = 120volts

I = 2A

R = ?

Note that R,V and I represents resistance, voltage and current respectively.

Substituting the above values into the formula.

V = IR

120v = 2×R

120= 2R

Making R the subject

R =120/2

R = 60 ohms

Hence the resistance of the toaster will be 60 ohms.

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
