MATLAB Command Window Basic Examples

• Example-1
• The voltage, v, across a resistance is given as
  (Ohms Law), vRi, where i is the current and R
  the resistance. The power dissipated in resistor
  R is given by the expression,
• P Ri2
• If R 10 Ohms and the current is increased
  from 0 to 10 A with increments of 2A, write a
  MATLAB program to generate a table of current,
  voltage and power dissipation.

• Example 2 Write a function file to solve the
  equivalent resistance of series connected
  resistors, R1, R2, R3, , Rn.
• The general form of a function in m-file is
• function variable(s) function_name (arguments)
• help text in the usage of the function

TRANSIENT ANALYSISRC NETWORK

• Example Assume that for Figure, C 10 µF, use
  MATLAB to plot the voltage across the capacitor
  if R is equal to (a) 1.0 kO, (b) 10 kO and (c)
  0.1 kO. (Vs10V)

• Example In Figure, if R1 20 O, R2 100O , R3
  50 O , and L1 4 H, L2 8 H and C1 250µF,
  find v 3( t) when w 10 rad/s.
