FIRST ORDER CIRCUITS

What is first order circuits?

     -can only contain one energy storage element (a capacitor or an inductor). the circuit will also contain resistance.

TWO TYPE OF FIRS ORDER CIRCUIT

   *RC circuit
   *RL circuit

                  SOURCE-FREE CIRCUITS 

-is one where all independent source have been disconnected from the circuit after some switch action. the voltages and currents in the circuit typically will have some transient response due to initial conditions

FOR RL Circuits

LEARNING'S:

    Wow! i learned a lot for this awesome circuits thank's for our GOOD looking teacher because of him i simply learned the process of electricity flowing to our small mansion. I learn how determine the currents passing through our appliances and how many voltage needed on it. 

MAXIMUM POWER TRANSFER

What is maximum power transfer?

Maximum Power transfer

-States that to obtain maximum external power from a source with a finite internal resistance, the resistance of the load must equal the resistance of the source as viewed from its output terminals

The condition of maximum power transfer does not result in maximum efficiency.if we define the efficiency n as the ratio of power dissipated by the load to power developed by the source, then it is straightforward to calculate from  the above circuit diagram that

 Another example:

INDUCTOR

What is inductor ?

Inductor

-also called a coil or reactor,is a passive two-terminal electrical components which resists change in electric current passing through it

Formula:

        SAMPLE INDUCTOR

INUCTOR IN SERIES AND PARALLEL

 FOR PARALLEL

   sample figure:

CAPACITOR

CAPACITOR

-are one of the standard components in electronic circuits and a passive two-terminal electrical component used to store energy in an electric field.

Formula:

 -  Where Q is the charge on the conductor

 - V is the potential applied across the conductor

 - C is proportionally constant called as capacitance

if capacitor are connected in series, the formula is given by:

  

If capacitor are connected in parallel,the capacitance formula is given by:
