A toaster draws 12 A of current when plugged into a 110 V outlet. The toaster coils glow red
hot when the toaster is on.
a. What is its power output of the toaster?
b. What is the resistance of the toaster coils?
a. P = E*I = 110 * 12 = __ Watts.
b. R = E/I = 110/12 = __ ohms.
a. To find the power output of the toaster, we can use the formula: power (P) = current (I) x voltage (V). In this case, the current (I) is given as 12 A and the voltage (V) as 110 V.
So, the power output of the toaster can be calculated as follows:
P = I x V
P = 12 A x 110 V
P = 1320 watts
Therefore, the power output of the toaster is 1320 watts.
b. To find the resistance of the toaster coils, we can use Ohm's law, which states that resistance (R) is equal to voltage (V) divided by current (I). In this case, the voltage (V) is given as 110 V and the current (I) as 12 A.
So, the resistance of the toaster coils can be calculated as follows:
R = V / I
R = 110 V / 12 A
R = 9.17 ohms
Therefore, the resistance of the toaster coils is approximately 9.17 ohms.
