The headlamp of a car takes a current of 0.4f from a 12volt supply. The energy produced in 5 minute is what

1 answer

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.
