What is function of snubber circuit?
capable of resetting the transformer as well as eliminating leakage inductance voltage spike across the switch
What should be observed when connecting a volteter into a DC circuit?
polarity is of major importance in dicect current circuits. <<>> When using meters please remember that a volt meter does not connect into a circuit, the leads are placed across the component that you are measuring. It is an amp meter that connects into the circuit, becoming part of the circuit, to measure the current flowing through that circuit.
The voltage measured directly across an open switch in a circuit will be?
The voltage measured across an open in a series circuit is the equivalent of the sourse voltage.
What is the voltage of a series circuit with four voltage drops of 30 volts?
there is 120V across the 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.

What is the effective filter to remove impulse noice?
A: A spike noise can be handled with a snubber of the proper value. Snubber is to be put across the source at the spike to absorb the energy usually an RC will suffice.
How do you connect parallel circuits?
A parallel circuit is realized by connecting two elements to the same nodes so the potential difference across their terminals can be the same.
Does voltage flow across a circuit or is it impressed across a circuit?
Voltage is impressed across a circuit. Current flows through a circuit.
What is the purpose of using the series resistance in a clipping circuit?
something to drop the excess voltage across while clipping.
How do you measur voltage in a circuit?
Place a voltmeter across the two points in the circuit you want to measure, and measure it. Be sure to know the expected voltage so that you can take appropriate safety precautions, and know the impedance of the circuit so that you can choose a voltmeter with a high enough internal impedance that it will not significantly affect the circuit.
Four 9 volt batteries are connected in paralell how much voltage is active across the circuit?
9 Volts. By connecting this way you increase current potential (amperage) but not voltage.

What will a ammeter indicates if it is connected in parallel?
Connecting an ammeter in parallel with a circuit element is hazardous. Because of its negligible resistance, it is equivalent to applying a short circuit across that element, and the resulting current through the ammeter may severely damage the instrument if it is not fused.
Do You measure current across a circuit?
A current flows through, not across, a circuit. And, yes, you can measure it using an ammeter.
Is it better to have a high or low resistance across a circuit breaker?
A circuit breaker is supposed to protect the more valuable component the circuit is connected to. Too low a resistance, a minor glitch (spike) will break the circuit and stop the device from working. Too high a resistance, no glitches, no matter how large (a child sticking a paper clip into the wall sockets, for example), will break the circuit and the device (child) may get damaged. Each circuit will have a purpose (power load), and the circuit breaker should be chosen for that purpose with some tolerance. A free standing closed circuit breaker should have no resistance across its internal contacts. The main purpose of a circuit breaker is to protect the conductors that supply the load. If the current going to the load becomes greater that the amperage rating of the wire the circuit will open thereby saving the conductors from damage. Once the load current is below the wire rating ampacity, the breaker can be reset for normal operation.
In what part of the circuit do the electric charges releases most of their energy?
The component with the highest resistance in a series circuit will have, or "drop" the most voltage across it. All of the components in a series circuit will have the same amount of current flowing through them but not the same voltage drops if the resistances are different. More resistance more voltage across it, less resistance, less voltage across it.
