Answer:

60 ohms

Step-by-step 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.
