Why would an inverter overload a circuit?
The only way an Inverter could overload a circuit would be on the supply side. The fusing/protection for the inverter is incorrect.
What is thyristors?
A thyristor is a part of a alarm circuit you use it so the alarm stays on
What circumstances led to the invention of the transistor in 1947?
before the invention of transistor,thyristor was used instead of transistor but thyristor produces more heat in the circuit and size is more when compared to transistor
What does a thyristor works as a circuit breaker?
A thyristor is a type of semi-conductor and is used in a circuit to control the application of electrical power to a load. They are often found as the switching element in light dimmers and can be used as control elements in power supplies (variable or regulated). Types of thyristors are diacs, triacs, sidacs and SCRs (silicon controlled rectifier).
What is the name of a logic gate that will invert a signal from a 0 to a 1 when added to a circuit?
a not gate or an inverter
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 does forced commutation mean?
The term "Forced commutation" is used when a thyristor is turned off using external components. If a thyristor is used in a DC circuit, when first turned on, it will stay on until the current goes to zero. To turn off the thyristor it is possible to use a Forced commutation circuit. The circuit creates a reverse voltage over the thyristor (and a small reverse current) for a short time, but long enough to turn off the thyristor. A simple circuit consist of a precharged capacitor and a switch (e.g. another thyristor) parallel to the thyristor. When the switch is closed, the current is supplied by the capacitor for a short while. This cause a reversed voltage over the thyristor, and the thyristor is turned off.

What is a line commutation?
it is the natural commutation ...by making open circuit or short circuit on the thyristor to make it turn off.

Why now-days fluroscent light does not has choke and starter?
it have electronic inverter circuit
How would a ammeter be connected in a circuit?
An ammeter is always connected in series in the circuit.
What is a circuit in which loads are connected side by side?
A circuit in which loads are connected side by side is known as a parallel circuit.
Can a thyristor work as a circuit breaker?
A thyristor is primarily a very fast "switch-on" device and is not designed to be used as a "switch-off" device.A circuit breaker is primarily a "switch-off" device which is used to automatically break the flow of current from a source to a load whenever the amount of current exceeds the rated current value of the breaker.So, because a thyristor does not, all by itself, "open" a circuit, a thyristor cannot be used to work as a circuit breaker.NotesCurrent flow through a thyristor can only stop if - external to it - the current flowing through it gets reduced to below its minimum holding current or, of course, to zero, as would happen either:i) if the load was disconnected from it by a separate circuit breaker that is wired into the circuit between the thyristor and the load;orii) if the source was disconnected from it by a separate circuit breaker that is wired into the circuit between the supply and the thyristor.Further notesA thyristor is designed to close or "make" a circuit whenever:a) an appropriate value of trigger voltage is put onto its gateand then only if:b) the current from the source to the load can flow through it in its "forward" direction.One way of ensuring it automatically disconnects the load from the source is to use an alternating current supply and always "trigger" the thyristor so that it turns on during each positive-going part of each ac cycle.Then, whenever the ac supply voltage returns to zero at the end of each positive half-cycle (after which it goes into the negative half-cycle) the thyristor will automatically break any further flow of current.By using other electronic circuitry to determine exactly when the gate is triggered (earlier or later in each positive-going part of each cycle) the amount of power supplied to the load can be controlled very accurately.That is why the main application for thyristors is to provide a precisely controlled way too use alternating currents to allow varying amounts of power to be supplied to electrical loads.
What is a circuit breaker connected in?
it is connected in a box
How are voltmeters connected to a simple series circuit?
Voltmeters are connected to simple series circuits the same way they are connected to any circuit. They are connected in parallel with the portion of the circuit for which you wish to measure the voltage drop.
