Capacitor

Edit
  • Capacitor: Capacitor is an arrangement of primarily two conductors for storing large amount of electric charge.
  • Capacitance: Ratio of charge is given to the potential difference applied across is called be capacitance.

    Capacitance is defined as,

  • Capacitance of an iso…

Effects of Current and Heating Effect of Current

Edit

Effects of Current:

  • Electric current is the following effects in a conductor:
    1. Heating effect
    2. Chemical effect
    3. Magnetic effect
    4. Heating effect of current:
  • An electric current is passing through a conductor which becomes hot after some time and then produces heat. This is due to the conversion of some of the electrical energy that passes through the conductor, into heat energy. Tis process is called the heating effect of current.
  • Electric current is define as the flow of electrons in a circuit.

The heat produced in a conductor that a current flows through it, is found to depend directly on the following factors:

  • Strength of the current
  • Resis…
