An ammeter indicates the current for a toaster is 5.0 amps when the toaster is connected to 120-V circuit. How much energy is given off by the toaster in 42.0 seconds?

show all the calculations leading to your answer

energy=power*time=volts*amps*timeinSeconds

To calculate the energy given off by the toaster, we need to use the formula:

Energy = Power × Time

First, we need to calculate the power consumed by the toaster. The formula for power is:

Power = Current × Voltage

Given that the current is 5.0 amps and the voltage is 120 volts, we can calculate the power used by the toaster:

Power = 5.0 A × 120 V
Power = 600 watts

Now, we can use the calculated power and the given time (42.0 seconds) to find the energy:

Energy = Power × Time
Energy = 600 W × 42.0 s
Energy = 25,200 joules (or 25.2 kJ)

Therefore, the toaster gives off 25,200 joules (or 25.2 kJ) of energy in 42.0 seconds.
