equivalent resistance of a parallel combination R ′ = R R = 33000 . Ohm We know that, ʹ ʹ ( ʹ) = ( ) + (R ′ ) ∆ R ’ ’ Substituting the value, = . + . = .
% - - - - Appendix Then, Time taken to cover this distance = / s = s . Draw the resultant direction of the two unit vectors an ˆ d j . Use a -dimensional Cartesian co-ordinate system. Is ˆ i j + a unit vector?
By using the triangular law of addition ˆ i j + as shown in the following figure, The definition of unit vector is ˆ A . ˆ A = But here,
