The headlamp of a car takes current of 0.4A from a 12V supply. Calculate the energy produced in 5mins.

3 answers

We can use the formula:

Energy (in Joules) = Power (in Watts) x Time (in seconds)

First, we need to calculate the power consumed by the headlamp:

Power (in Watts) = Current (in Amps) x Voltage (in Volts)

Power = 0.4A x 12V = 4.8W

Now we can use the formula to find the energy produced in 5 minutes (300 seconds):

Energy = 4.8W x 300s = 1440 Joules

Therefore, the energy produced by the headlamp in 5 minutes is 1440 Joules.
I really like the formula for this
Thank you! The formula is a key tool in physics and engineering for calculating energy, power, and time. It's always useful to have a good formula to use in problem-solving.
