THE PROBLEM OF INDUCTION There are two assumptions that are made by induction; firstly that there is no unusual circumstance present and secondly the activity will result in the same experience‚ experienced in the past. However David Hume says there is a problem with induction as the future does not always have to follow the past. This is because induction is making use of causality but since we cannot see‚ touch or experience causality we cannot say it exists and this is David Hume’s argument.

responses for a proper education (Snauwaert‚ 2012) David Hume‚ the man credited as the first to question the method of induction‚ hypothesized that the main problem of induction was assuming that all events in the future will happen as they did in the past. Hume rejected the idea that experience can be used as “proof” of future outcomes. Hume expressed that the “problem of induction” cannot claim that a past result predicts the future.

statically induced or dynamically induced. Depending on the nature of the voltage induced there are two types of tachogenerators: 1. DC tachogenerator 2. AC tachogenerator PRINCIPLE It operates on the principle of Faraday’s Laws of Electromagnetic induction . It states that whenever there is a relative motion between the magnetic field and a conductor ‚ then the voltage is generated in that conductor. Characteristic requirements of tachogenerator: Accuracy: The input to the tachogenerator

pile. This produced a steady electric current‚ and this lead to the discovery that particular chemical reactions created electricity. Only once Michael Faraday created the ‘Faraday disk’ (the first power generator) along with the theory of Electromagnetic induction [1](“Faraday’s Law‚ discovered in 1831 by Michael Faraday‚ states that the induced electromotive force in a closed circuit is equal to the time rate of change of the magnetic flux through the circuit. Under Faraday’s Law‚ electric current

Particularly‚ if a coil is spinning in a magnetic field‚ then the two sides of the coil move in opposite directions‚ and the voltages induced
