The headlamp of a car takes a current of 0.4A from a 12V supply. The energy produced in 5Minute is ?
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
0.4 A * 12 V = 4.8 W = 4.8 J/s
4.8 J/s * (5 min * 60 s/min) = ? Joules
I need the solution to that question
Thr question is not complete.calculate the total energy developed in 5 minutes by the system below. Calculate the value of I andV
SOME QUESTION
Thanks for solving it
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.
