Sep 30, 2024 · Graphs for a.c. generators. Extended tier only. The output of an a.c. generator can be seen on a graph of e.m.f. against time, or angle of rotation. The shape of the graph is a sine or cosine curve, depending on the starting position of the coil. When it starts from a horizontal position (e.m.f. is at a maximum), the graph is a cosine curve

AC generator is a machine that converts mechanical energy into electrical energy. The AC Generator’s input supply is mechanical energy supplied by steam turbines, gas turbines and combustion engines. The output is an alternating electrical power in …

Let's explore the EMF and flux equations of an AC generator and draw graphs for them. Khan Academy is a nonprofit organization with the mission of providing ...

A.C. generator is an electromagnetic device which transforms mechanical energy into electrical energy. It consists of a rectangular coil of wire which can be rotated about an axis. The coil is located between the poles of two permanent magnets.

Hint: An A.C. generator is an electronic device used to convert mechanical energy into electrical energy using the principle of electromagnetic induction. Construct the diagram by schematic analyses of its working and thus include all its essential components.

An electric generator rotates a coil in a magnetic field, inducing an emfgiven as a function of time by \(emf=NABωsinωt,\) where \(A\) is the area of an \(N\)-turn coil rotated at a constant angular velocity ω in a uniform magnetic field \(B\).

The output of an alternator can be represented on a potential difference-time graph, with potential difference on the vertical axis and time on the horizontal axis.

The output of a generator can be represented on an induced current–time graph which is shown below. It shows four different positions of the coil of the generator, and the corresponding...

Interactive 3D Model: The simulation features a 3D model of an AC generator. This allows students to visualize the different components (stator, armature, slip rings, brushes) and their interactions.
