Without knowing what they is, nobody will ever be able to answer your question.
A 'core type' transformer core is one in which the primary windings and secondary windings are placed around each of the limbs, as opposed to a 'shell type' core, in which the two windings are placed across the centre core. A core-type core is a magnetic circuit equivalent to an electric series circuit, whereas a shell-type core is equivalent to an electric parallel circuit. This is better answered with a diagram, so I suggest that you do a search on the internet.
if we remove a resistor from the parallel connection the effective resistance value will be increased.
Because the flux leakage is less in shell type than that in core type T/F.Additional AnswerA shell-type core's magnetic circuit is equivalent to a parallel electric circuit, so it has a lower reluctance compared to a core-type core of similar cross-sectional area.
The current flowing through a series circuit is (voltage between the circuit's ends) / (sum of all resistances in the circuit). The current is the same at every point in the series circuit.
There are four types of circuit: series, parallel, series-parallel, and complex.
What do you mean by a 'parallel delta' circuit -is there such a connection.
In principle, it is infinite. I have not connected a parallel circuit in ages.
In the series connection and how there is multiple paths or branches on parallel circuits but in a simple circuit, there is one path.
yes it is
These two tests are performed on a transformer to determine (i) equivalent circuit of transformer(ii)voltage regulation of transformer(iii) efficiency of transformer. The power required for theseOpen Circuit test and Short Circuit test on transformeris equal to the power loss occurring in the transformer.

The equivalent resistance is the overall effect all of the resistances in a circuit has. Put another way, it is the value a single resistor in a circuit would have to be in order to have the same effect as all of the resistors resistors combined in a given circuit.
Yes, a battery operated toy has a parallel circuit - the battery is in parallel with the toy. In fact, this is true for any system where there is a single equivalent source and a single equivalent load. While it is true that this is also a series circuit, by Kirchoff's current and voltage laws a simple series circuit is also a simple parallel circuit.
Excitation current Io = Iw + Iu
In a parallel circuit, the current flow is independent in each branch.
A voltmeter should be connected in a parallel connection
