If C1 is the coefficient of speed fluctuation of a flywheel then the ratio of \(\frac{{{\omega _{max}}}}{{{\omega _{min}}}}\) will be
1
\(\frac{{1 - 2{C_1}}}{{1\; + \;2{C_1}}}\)
2
\(\frac{{2 - 2{C_1}}}{{2\; + \;2{C_1}}}\)
3
\(\frac{{1\; + \;2{C_1}}}{{1 - 2{C_1}}}\)
4
\(\frac{{2\; + \;{C_1}}}{{2 - {C_1}}}\)
