Study Notes
Aryaman Pradhan's Physics Project
- The title of Aryaman Pradhan's physics investigatory project is not specified.
- Aryaman Pradhan was guided by Mr. S. K. Goyal in his physics project.
- Aryaman Pradhan studied at Delhi Public School, Noida.
Inductance
- The main subject of Aryaman Pradhan's project is inductance.
- Dr. R. K. Sharma signed the certificate as an external examiner.
- Mrs. Pankajini Panda played the role of an internal examiner in Aryaman Pradhan's project.
Inductor Construction
- The four basic factors of inductor construction determining the amount of inductance created are:
- Number of turns of the coil
- Permeability of the core material
- Cross-sectional area of the coil
- Length of the coil
Inductance Definition
- Inductance is the property of a conductor that opposes a change in current by inducing an electromotive force (emf).
- The self-inductance of a coil is given by the formula L = (μ × N × A) / l.
Induction and Self-Induction
- When an emf is induced in the same circuit in which the current is changing, the induced emf opposes the change in current.
- Self-induction results from the changing magnetic flux within the coil itself.
Henry's Law
- Henry's Law states that a circuit will have an inductance value of one Henry when an emf of one volt is induced in the circuit.
Self-Inductance Dependence
- Self-inductance depends on the geometrical structure of the coil, including its shape, size, and material.
Inductor Function
- An inductor opposes the change of current flowing through it by inducing an electromotive force (emf) that counteracts the change.
- The induced emf is proportional to the rate of change of the current.
