which electric element should be used so as to open the closed electric circuit
A simple circuit consists of a source of electro motive force ( EMF or voltage V ) This could be a battery,dynamo or solar cell. The circuit should do something, like light a lamp. For the lamp to glow there must be a flow of electrons called an electric current measure in Amperes (I). For the current to flow the circuit must form a closed loop, like a daisy chain. A switch is a device that breaks this loop and controls the state of the circuit. Closed circuit, switch closed, = lamp on Open circuit, switch not closed = lamp off
The thyristor is basically used a switch in an AC circuit to control the amount of power fed to the load. To turn on this switch an "electric" pulse should be applied to the Gate terminal of the Thyristor. A circuit which supplies the "electric" pulse is called the firing circuit.
its is an oject that can be used in a cicuit board, this object should allow an electric current to flow through it
If the circuit of the panic button is monitored for a break in its circuit, the contacts will be in a N.C. configuration. There will need to be a relay in the circuit that is kept energized by the buttons closed contacts. When the relay drops out, its N.C. circuit contacts will activate the panic buttons load. If the panic button has no monitoring features then the contacts across the button will be wired in the N.O. configuration. When the button is pushed the circuit closes.
An 'isolation transformer' is a 1:1 ratio mutual transformer. It electrically isolates the secondary circuit from the primary circuit without changing the voltage level. A bathroom shaver socket uses an isolation transformer.
A switch, circuit breaker, fuse, or switching transistor can do that.
there should not be any diff.because

Of course they should. You are not doing anything in there you should not be doing, are you?
A switch basically represents a gap in the electric circuit. Electric current can pass through a circuit only if it is complete. An incomplete circuit can never pass a current through it. When the switch is in the 'off' position, the circuit has a break (gap) in it. When you put the switch in 'on' position, the circuit wire join and the circuit gets completed.
An ammeter should be placed in series, between the element you want to know the current of and the node the element was attached to before.

To get an open circuit to work and light a light bulb, turn the switch on. Or hardwire it to power up the lamp. If the battey or other power source is good, and so is the lamp, make sure all the connections are good and that the conductor (wire) isn't broken. With all the components in good shape and properly connected, the light should be glowing.
Cathode ray oscilloscope(CRO) is a device used to see the voltage across a particular element of your circuit and the wave form can also be seen on CRO. But you actually cannot measure the current using CRO as it is meant to give the voltage levels across any element in eletrically enegized circuit. however Digital Multimeter can do this job. But while using DMM to measure current one thing should be kept in mind that your circuit should be linear so that if you break the circuit to find current in series the current could not change in circuit.
In a series circuit, if you open a bulb, current loop will be broken. So, current cannot travel all the wayback, hence no output. But in a parallel circuit, current will be only shared with parallel circuit, but the loop remains closed even if you remove the bulb. So, no change occurs.
Under normal conditions, the stop button should not be interrupting the circuit, so the circuit must be closed. When the stop button is used, it should open the circuit. it is a N.C. switch because this follows its' purpose.
Not touching a live conductive part of a circuit is a great way to prevent you from receiving an electrical shock! Along with this the circuit breaker should trip if there is a fault on the circuit, or a GFCI if there is no ground in the circuit
