The headlamp of a car takes a current of 0.4A from a 12V supply. The energy produced in 5Minute is ?

Answer 1

0.4 A * 12 V = 4.8 W = 4.8 J/s

4.8 J/s * (5 min * 60 s/min) = ? Joules

Answer 2

I need the solution to that question

Answer 3

Thr question is not complete.calculate the total energy developed in 5 minutes by the system below. Calculate the value of I andV

Answer 4

SOME QUESTION

Answer 5

Data
I=0.4
V=12
T=5min-5×60
R=?
V=ir
12=0.4×r
12=0.4r
R=12÷0.4
R=30
Formula
I(square)RT
0.4×0.4×30×300
=1440j

I don't know how to solve it

Answer 11

1440j

Answer 12

The total energy developed in 5 minutes by the system can be calculated using the formula:

Energy = I^2 * R * T

Where I is the current in Amperes, R is the resistance in Ohms, and T is the time in seconds.

Given data:
I = 0.4 A
V = 12 V
T = 5 minutes = 5 * 60 seconds = 300 seconds

We can calculate the value of resistance R using the formula: V = IR
R = V/I = 12/0.4 = 30 Ohms

Now we can substitute the values of I, R and T in the energy formula and get:
Energy = 0.4^2 * 30 * 300 = 1440 Joules

Therefore, the total energy developed in 5 minutes by the system is 1440 Joules.
