To calculate the energy produced in 5 minutes, we need to use the formula:
Energy = Power x Time
Where Power is the rate at which energy is consumed (in Watts) and Time is the duration for which the power is consumed (in seconds).
First, we need to convert the current from amperes (A) to Watts (W) using Ohm's law:
Power = Current x Voltage
Power = 0.4 A x 12 V = 4.8 W
Now we need to convert the time from minutes to seconds:
Time = 5 minutes x 60 seconds/minute = 300 seconds
Finally, we can calculate the energy produced:
Energy = Power x Time
Energy = 4.8 W x 300 s = 1440 J
Therefore, the energy produced by the headlamp of the car in 5 minutes is 1440 Joules.
The headlamp of a car takes a current of 0.4f from a 12volt supply. The energy produced in 5 minute is what
