Acoil with an inductance of 2.8 h and a resistance of 12 ω is suddenly connected to an ideal battery with ε = 89 v. at 0.086 s after the connection is made, what is the rate at which (a) energy is being stored in the magnetic field, (b) thermal energy is appearing in the resistance, and (c) energy is being delivered by the battery?

The stored energy is 140.7 watt.

The thermal energy is 62.7 watt.

The delivered energy is 203.4 watt.

Explanation:

Given that,

Inductance = 2.8 H

Resistance = 12 Ω

Potential

Time = 0.086 s

(a). We need to calculate the energy stored in the magnetic field

Using formula of current

Using formula of energy

On differentiating

Again differentiating

Put the value into the formula

(b). We need to calculate the thermal energy

Using formula of thermal energy

Put the value into the formula

(c). We need to calculate the delivered energy by the battery

Using formula of energy

Hence, The stored energy is 140.7 watt.

The thermal energy is 62.7 watt.

The delivered energy is 203.4 watt.

Consult

Explanation:

RICA is the acronym for Responsibility, Inform, Consult and Accountability. For different projects different categories are provided based on their requirement of involvement in the project. In the new project the IT department in the company provides inputs such as new software application. This work falls under consult in RICA matrix.

Responsibility is based on completion of the given work. Accountability to provide a final answer for the work done. Consult is providing feedback and contribution to the activity. Inform to person who requires information update.
