ELECTRIC CURRENT, ELECTRIC POTENTIAL, RESISTANCE

 ELECTRIC CURRENT

  • The continuous flow of electrons constitutes CURRENT.
  • It denotes by "I" and its unit is AMPERE(A).
  • Current is also treated as CHARGE/TIME.
  • So the unit is also COULOMB/SEC.

ELECTRIC POTENTIAL

  • Defined as the work done in bringing a unit positive charge from infinity to that point against the electric field.
  • It denotes by "V" and its unit is Volt(V).

RESISTANCE

  • The property of a conductor  by which it opposes the flow of current.
  • It denotes by "R" and its unit is OHM( Ω).
  • Resistance (R)= Voltage (V)/ Current (I).

TRANSFORMER RATING CALCULATION

Image
 TRANSFORMER RATING CALCULATION In this BLOG, we are going t discuss about the Calculation of   TRANSFORMER RATING : For Eg:- Maximum Load = 400KW. Diversity Factor = 0.7 Therefore, Expected Load in KW = 400*0.7 = 280KW Expected Load in KVA = 280/ 0.9 = 311KVA (Power Factor Considered as 0.9) 85% Loading Capacity is considered. Required KVA Rating = 311/ 0.85 = 366KVA Therefore, 400KVA transformer is used.  (400KVA is the n ext Available Rating above 366KVA) For More Topics: Follow Us On: FACEBOOK

CONDUCTANCE & CONDUCTIVITY

Image
CONDUCTANCE It is the measure of how easily the current will flow through the conductor. The reciprocal of Resistance is called CONDUCTANCE and is denoted by "G" . Its unit is "MHO" or "SIEMENS".          G = 1/R = I/V. CONDUCTIVITY Conductivity or SPECIFIC CONDUCTANCE is the reciprocal of specific resistance. It represented as σ (SIGMA) and its unit is Mho/Mtr. σ  = 1/  ρ. For More Topics: Follow Us On: FACEBOOK

LAW'S OF RESISTANCE

Image
LAW'S OF RESISTANCE The RESISTANCE of a Conductor varies, Directly with its LENGTH . Inversely to its CROSS-SECTIONAL AREA. Depends on NATURE of the materials. Depends on the TEMPERATURE.                                       R  ∝  L,  R  ∝  1/ A                                       R   ∝  L/A                                       R  =  ρ  * (L/A) Where   ρ is called SPECIFIC RESISTANCE (RESISTIVITY) and its unit is Ohm-Mtr .
