An industrial battery is charged over a period of several hours at aconstant voltage of 120 V. Initially, the current is 10 mA and increaseslinearly to 15 mA in 10 ks. From 10 ks to 20 ks, the current is constant at 15 mA. From 20 ks to 30 ks the current decreases linearly to 10 mA.At 30 ks the power is disconnected from the battery.1. a) Sketch the current from t=0 to t=30 ks.2. b) Sketch the power delivered to the battery from t=0 to t=30 ks.3. c) Using the sketch of the power, find the total energy delivered tothe battery.

Electrical Heating Unit

The conversion of electrical energy to heat energy is known as electric heating. The heating system that converts the electrical energy to heat energy for various application is called electrical heating unit. Electricity is employed as the firing mechanism in electric heating systems, which transforms electric current to heat. Electric heaters have heating elements in the form of electric resistors.
