A resistor connected to a 12V battery draws a current of 2A. The energy dispatched in the resistor in 5 minutes is ___.
Answer Details
To calculate the energy dispatched in the resistor, we need to use the formula:
Energy = Power x Time
Where Power is the amount of electrical power consumed by the resistor, and is equal to the product of the voltage across the resistor and the current flowing through it:
Power = Voltage x Current
In this case, the voltage across the resistor is 12V, and the current flowing through it is 2A. Therefore, the power consumed by the resistor is:
Power = 12V x 2A = 24W
Now, we can substitute this value of power along with the given time of 5 minutes into the formula for energy:
Energy = 24W x 5min x 60s/min = 7,200J
Therefore, the energy dispatched in the resistor in 5 minutes is 7,200J.
is the correct answer.
