Among the legitimate, referent, reward, coercive, expert power, Which type of power do you find most

Among the legitimate, referent, reward, coercive, expert power, Which type of power do you find most effective? Which type of power do you think that you have? Do you use it? If so, in what situations? How could you improve your leadership and management skills now that you have a better understanding of the types of power and how they are applied? Remember, always add the ‘whys’ with the ‘whats.’
