A battery can provide a current of 4.60 A at 3.40 V for 2.50 hr. How much energy (in kJ) is produced? 1st attempt kJ Energy

Respuesta :

Answer:

The energy produced equals 140.760 kJ

Explanation:

The relation between power, current and voltage is

[tex]Power=Current\times Voltage[/tex]

Applying the given values in the relation above we get

[tex]Power=4.60\times 3.40=15.64W[/tex]

Now Since [tex]Power=\frac{Energy}{Time}\\\\Energy=Power\times Time[/tex]

Again applying the calculated values we get

[tex]Energy=15.64\times 2.50\times 3600=140760Joules=140.76kJ[/tex]
