A 6V radio with a current of 2A is turned on for 5 minutes. Calculate the energy transferred in joules

Respuesta :

Answer:

R=V/I=6/2=3ohm

time =5minutes =5*60=300seconds

I=2A

Heat =I^2Rt=(2)^2*3*300=4*900=3600J

We have that Hence,the energy transferred in joules is mathematically given

E=0.04Joules

From the question we are told

A 6V radio with a current of 2A is turned on for 5 minutes. Calculate the energy transferred in joules

Generally the equation for the Power is mathematically given as

[tex]P=IV\\\\P=6*2\\\\P=12W[/tex]

Generally the equation for the Energy is mathematically given as

[tex]E=\frac{P}{t}\\\\E=\frac{12}{5*60}\\\\E=0.04Joules[/tex]

Hence,the energy transferred in joules is mathematically given

E=0.04Joules
