The head lamp of a car takes a current of 0.4A from a 12v supply energy produce in 5m is

Answer 1

We can calculate the energy produced by the headlamp using the formula:

Energy (E) = Power (P) x Time (t)

First, we need to calculate the power used by the headlamp. Power is given by the formula:

Power (P) = Current (I) x Voltage (V)

In this case, the current is 0.4A and the voltage is 12V:

P = 0.4A * 12V = 4.8W

Now we can calculate the energy produced in 5 minutes (300 seconds):

E = 4.8W * 300s = 1440 Joules

Therefore, the headlamp of the car produces 1440 Joules of energy in 5 minutes.
