# What is induced subgraph?

## Answer

###### April 25, 2008 7:17PM

Any subset X ⊆ nodes(G) induces a subgraph G[X] of G, where G[X] has nodes X and G[X] contains all arcs of G which join nodes in X.

G′ is a full (or induced) subgraph of G if G′ = G[X] for some X ⊆ nodes(G).

### How do you differentiate induced emf from induced current?

An induced electromotive force (emf) is an induced voltage.
Voltage (emf) causes current flow, and this induced voltage will
cause a current that is called the induced current.
We might also add that the induced current will cause a magnetic
field to expand about the current path, and this field will "sweep"
the conductor. The sweeping of the conductor by that expanding
magnetic field will set up an emf that will oppose the emf that was
creating it.
Comment
Technically, there is no such thing as an 'induced
current'. It is voltage that is induced. Any current
flows as a result of that induced voltage being applied to a load.
But that current is certainly NOT induced!

###### Asked in Physics

### How was current produce or induced?

Current is induced and not produced. when an electric wire is
passed through magnetic field the current is induced in the
electric wire, this electric wire is enamelled copper conductor of
a rotor.
Answer
Current is never 'induced' into a conductor. It is a
voltage that is induced. If that conductor is then part of a
complete circuit, then the induced voltage will cause a current to
flow. The induced voltage will occur even when the conductor is
open circuited.

### What determines whether an induced current is a direct current or an alternating current?

There is no such thing as an 'induced current'. What is
'induced' is a voltage. The direction of the induced voltage
is determined by the direction of the changing current that induces
that voltage, because the induced voltage will always act to oppose
that change in current. So, if the current is increasing,
then the direction of the induced voltage will act to oppose
the increase in current. If the current is decreasing, then
the direction of the induced voltage will act to sustain
that current.

### Difference between statically and dynamically induced emf?

STATICALLY INDUCED EMF
The emf induced in a coil due to change of flux linked with it
(change of flux is by the increase or decrease in current) is
called statically induced emf.
Transformer is an example of statically induced emf. Here the
windings are stationary,magnetic field is moving around the
conductor and produces the emf.
DYNAMICALLY INDUCED EMF
The emf induced in a coil due to relative motion of the
conductor and the magnetic field is called dynamically induced
emf.
example:dc generator works on the principle of dynamically
induced emf in the conductors which are housed in a revolving
armature lying within magnetic field

###### Asked in Electrical Engineering

### Who formulated a law for determining the direction of the induced current in a conductor?

There is no such thing as an 'induced current'. What is
'induced' is a voltage. If the conductor into which that voltage is
induced forms a complete circuit, then a current will result. But
it's the voltage that's induced, NOT the current!
The direction of the induced voltage is explained by Lenz's Law
which, in simple terms, tells us that the direction of the inducted
voltage is always such that it will oppose the change in current
that causes it. So the induced voltage will oppose any increase in
current, but will act in the same direction as a reduction in
current.
