A choke coil placed in series with an electric lamp in an ac circuit causes the lamp to become dim why is it so?

The light is getting dim because the choke is using the energy the lamp should be using. The purpose of the choke is to remove transients; if it is using power at 50 or 60Hz, this is not desirable.
My guess is this lamp is using a new energy efficient (not incandescent) light bulb? If this is the case, don't.
If this is a choke you added to the lamp, then perhaps it's the wrong type choke (too large inductance).
If you added this, it could be that you inadvertently inserted resistance in the lamp wire. Check to make sure nothing is getting hot around your new wiring. A bad solder point could cause this to some degree.

What core type and shell type?
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.
A screwdriver placed across two wires in a circuit creates a circuit?
Depending on where in the circuit the screw driver is placed it could be used as a switch or it could short the circuit out.

Can inserting a resistor in a circuit have an effect similar to an short circuit?
It creates an extra load to the circuit if placed parallel to other circuits. this load approaches the equivalent of a short circuit as the resistance value placed there reduces.
What Is a core-core type transformer?

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.
What will happen if a paper clip made of metal is placed in an electric circuit?
Metal is an excellent conductor of electricity. So a metal paper clip placed in an electric circuit will conduct whatever current may be in that circuit. If the current is very large, the paperclip may get hot.

How is a circuit formed?
The amount of electric potential energy per unit of charge that would be possessed by a charged object if placed within an electric field at a given location.See related links below.

What safety devices that stop the flow of electric currents?
There are two types. A fuse is a piece of wire that is thinner than the circuit it is placed in series with. Any excessive current causes the fuse to melt and this cuts off the power. The fusing current is somewhat unpredictable. A circuit-breaker is a resettable device that can be set to interrupt the supply at a fixed amount of current.

What is the process that causes a stalk of salary to become limp and rubbery when placed in salt water?
because of the saltyness of the salt
What causes Trunk to open when gearshift is placed in drive?
An electric wiring short. You have a frayed wire someplace making contact and popping the trunk open.
What components are placed in an electrical circuit to control the amount of resistance in circuit?

What does a PCB do on a circuit?
A PCB (Printed Circuit Board) is the board on which components are placed and soldered into position. It doesn't do anything in a circuit, merely the foundation on which a circuit can be created.
Where should a timer be installed - at the electrical outlet or the end of a power cord?
The outlet would be the more often recommended place for it.An electrical timer can be placed anywhere within the circuit. Usually the timer would be placed at the front end of the circuit.
