આપેલ \(dc\) સ્ત્રોત ધરાવતા પરિપથમાં અવરોધ \(R_S\) નું મૂલ્ય કેટલું હશે?

  1. A \(\frac{{\left( {{V_i} - {V_L}} \right)}}{{\left( {n + 1} \right){I_L}}}\)
  2. B \(\frac{{\left( {{V_i} + {V_L}} \right)}}{{\left( {n + 1} \right){I_L}}}\)
  3. C \(\frac{{\left( {{V_i} - {V_L}} \right)}}{{n{I_L}}}\)
  4. D \(\frac{{\left( {{V_i} + {V_L}} \right)}}{{n{I_L}}}\)

Answer & Solution

Correct Answer

(A) \(\frac{{\left( {{V_i} - {V_L}} \right)}}{{\left( {n + 1} \right){I_L}}}\)

Step-by-step Solution

Detailed explanation

Voltage on resistor \(R_s\,=\,V_i\,-\,V_L\) or, \(({{I}_{L}}\,+\,n{{I}_{L}}){{R}_{s}}\,=\,{{V}_{i}}\,-\,{{V}_{L}}\) \(\therefore \,\,{{R}_{s}}\,=\,\frac{\,{{V}_{i}}\,-\,{{V}_{L}}}{(n+\,1){{I}_{L}}}\)
