The headlamp of a car takes a current of 0.4f from a 12volt supply. The energy produced in 5 minute is what
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.
To calculate the energy produced by the headlamp, we can use the formula:
Energy = Power x Time
Given:
Current (I) = 0.4 A
Voltage (V) = 12 V
Time (t) = 5 min = 5 x 60 s = 300 s (since 1 minute = 60 seconds)
First, we need to calculate the power (P) consumed by the headlamp using Ohm's Law:
P = I x V
P = 0.4 A x 12 V
P = 4.8 W
Now, we can calculate the energy (E) produced by the headlamp using the formula:
E = P x t
E = 4.8 W x 300 s
E = 1440 joules
So, the energy produced by the headlamp in 5 minutes is 1440 joules.
