Question
What is the resistance of a toaster that draws 10 amperes when connected to a 120 -volt circuit?
Step 1
The formula for resistance (R) in an electrical circuit is given by Ohm's Law, which states that R = V / I, where V is the voltage and I is the current. Show more…

(I) What is the resistance of a toaster if 120 V produces a current of 4.6 A?
ELECTRIC CURRENTS
Electric Current
The current through a toaster that is connected to a $120-\mathrm{V}$ source is $8.0 \mathrm{A}$. What power is dissipated by the toaster?
Current Electricity
Using Electric Energy
Using the formula power $=$ current $\times$ voltage, find the current drawn by a $1200-W$ toaster connected to 120 $\mathrm{V}$ . Then, using the method from the preceding problem, show that the resistance of the toaster is 12$\Omega .$
