Question 1 Report

A bread toaster uses a current of 4A when plugged in a 24oV line. it takes 1 minute to toast slices of bread. what is the energy consumed by the toaster
Answer Details
The energy consumed by the toaster can be calculated using the formula: Energy (E) = Power (P) x Time (t) We can find the power used by the toaster using the formula: Power (P) = Current (I) x Voltage (V) So, P = 4A x 240V = 960W Since the time taken to toast the bread is given as 1 minute, which is 60 seconds, we can now calculate the energy consumed: E = 960W x 60s = 57,600 J Therefore, the energy consumed by the toaster is 5.76 x 10^4 J (option A).
