What are the characteristics of a simple 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
What is the thyristor firing circuit?
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.
What is circuit conductor?
its is an oject that can be used in a cicuit board, this object should allow an electric current to flow through it
Should your panic button be wired to the no or nc terminal. It doesn't say in the instructions.?
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.
What is the operation of isolator?
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.
Which electric element should be used so as to open the closed electric circuit?
A switch, circuit breaker, fuse, or switching transistor can do that.
Is the potential difference across an electric circuit with no element drawing current from it the same at every pt?
Yes, in a circuit with no current draw, the potential difference is the same at every point in the circuit. This is due to the conservation of energy principle in electric circuits.

Classrooms should not have closed circuit cameras?
Of course they should. You are not doing anything in there you should not be doing, are you?
How does a switch control an electric device?
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.
Should you connect both ends of a battery in a circuit?
Yes, both ends of a battery should be connected in a circuit to create a continuous flow of electric current. When one end of the battery is connected to one terminal of a component and the other end to the other terminal, a closed circuit is formed, allowing electricity to flow and power the device.
How should an ammeter be placed in a circuit?
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.

Using a cathode ray oscilloscope how do you measure the current in an electric circuit?
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.
Why is one bulb set up along a parallel circuit actually a series 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.
Why start button is Normally open?
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.
What prevents you from receiving an electric shock?
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
