Question

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

Answer 1

The energy produced equals 140.760 kJ

Step-by-step explanation:

The relation between power, current and voltage is

`Power=Current* Voltage`

Applying the given values in the relation above we get

`Power=4.60* 3.40=15.64W`

Now Since
`Power=(Energy)/(Time)\\\\Energy=Power* Time`

Again applying the calculated values we get

`Energy=15.64* 2.50* 3600=140760Joules=140.76kJ`
