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' 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.
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.
What is the definition of a coulomb and how is it related to the concept of electric charge?
A coulomb is the unit of electric charge in the International System of Units (SI). It represents the amount of electric charge that flows through a conductor in one second when a current of one ampere is flowing. Electric charge is the fundamental property of matter that causes it to experience a force when placed in an electric field. The coulomb is used to quantify the amount of electric charge present in a system or flowing through a circuit.
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.
How an electric current is measured?
Electric current is typically measured using an ammeter, which is a device connected in series with the circuit. The ammeter measures the flow of electrons passing through a given point in the circuit, usually in units of amperes (A). The ammeter must be placed in series with the circuit to ensure that the current passes through it and can be accurately measured.
What is the space around a charged object where electric forces act?
The space around a charged object where electric forces act is known as the electric field. This electric field exerts a force on any other charged particles that are placed within it, causing them to experience an electric force.
What happens if you placed an insulator in an electric field?
An insulator does not conduct electricity, so it will not allow the flow of electric current through it. When placed in an electric field, the insulator will become polarized, but it will not allow the movement of charges like a conductor would.
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.
A sentence for the word electric charge?
an electrical charge is a physical property of matter which causes it to experience a force when near other electrically charged matter
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
An electrical circuit with components placed one after the other?

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 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.
