An electronic device is supplied with a chemical energy of 110Joules. 50 Joules was considered as dissipated energy. Deduce it useful energy ?

To find the useful energy, we need to subtract the dissipated energy from the total energy supplied.

Useful energy = Total energy supplied - Dissipated energy
Useful energy = 110 Joules - 50 Joules
Useful energy = 60 Joules

Therefore, the useful energy supplied to the electronic device is 60 Joules.

Useful energy is the energy that is used by the device to perform its intended function. In this case, the useful energy is the energy that is used to power the device and enable it to perform its functions.

Dissipated energy is the energy that is lost as heat or other forms of unusable energy. In this case, the dissipated energy is the energy that is lost as heat due to the operation of the device.

Chemical energy is the energy that is stored in the chemical bonds of the device's battery or other power source. In this case, the chemical energy is the energy that is stored in the battery that powers the device.

To deduce the useful energy, we can use the following formula:

```
Useful energy = Chemical energy - Dissipated energy
```

In this case, we have:

```
Useful energy = 110 Joules - 50 Joules
```

```
Useful energy = 60 Joules
```

Therefore, the useful energy of the electronic device is 60 Joules.
