How should a ammeter and voltmeter be connected in circuit?
Ammeter is coneccted in series with circuit but Voltmeter is connected in parallel.
What will happen to 1N4001 doide if a reverse voltage of 52 volts is impressed across it?
A: nothing should happen since a 1N4001 is capable to sustain 100v in the reverse direction. 52v is within the 100v reverse breakdown voltage.
Should an ammeter always be connected in parallel with a component?
No, an ammeter should never be placed in parallel with a component - it should always be placed in series, so that the current through the component is measured.If you place an ammeter in parallel with a component, you create a short circuit around the component. Depending on the rest of the circuit, you could damage the circuit, damage the ammeter, create a fire, etc. You certainly will affect the current through the component, and that is not what you want to accomplish.
Why the windings of an ammeter should be of thick wire?
because lots of current is likely to be flowing through them.however a shunt ammeter is easier to build than the direct ammeter as described above. in a shunt ammeter you use an ordinary meter wound with fine wire and put a small value shunt resistor across it to take almost all the current.
The rules of connecting voltmeter and ammeters in the circuit?
Connect ammeter in series and voltmeter in parallel to the circuit
When using the emergency bandage what should you do once the elastic bandage is placed thru the pressure bar?
reverse wrapping direction and continue bandaging the wound
When using the emergency bandaged what should you do once the elastic bandage is places through the pressure bar?
Reverse the wrappin direction, and continue bandaging the wound.
When using the emergency bandage what should you do once?
Reverse the wrapping direction, and continue bandaging the wound.
How should a ammeter and voltmeter be connected in circuit?
Ammeter is coneccted in series with circuit but Voltmeter is connected in parallel.
How would you connect an ammeter if you want to measure the current coming through some device in a circuit?
HOW TO CONNECT AN AMMETER Always connect an ammeter in SERIES in a circuit. Always ensure that the ammeter has a higher reading range than the expected current load, including start-up spikes. An ammeter expected to read a steady current of 13A should have a max range of 20A.
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.
Why do ammeter resistanse is very small?
An ammeter with a large resistance will affect the circuit that it is trying to measure. The ideal ammeter (or any measuring tool) should not affect what is being measured.
What should you do once the bandage is placed through the pressure bar?
Reverse the wrapping direction, and continue bandaging the wound.
How do you use an ammeter?
The Positive side of the Ammeter should be connected to the positive side of the battery and the Negative side should be connected to the Globe/Conductor/Insulator to provide a valid reading.
What will happen to 1N4001 doide if a reverse voltage of 52 volts is impressed across it?
A: nothing should happen since a 1N4001 is capable to sustain 100v in the reverse direction. 52v is within the 100v reverse breakdown voltage.
How can the direction of rotation of a DC shunt motor be reversed?
DC shunt motor can be reversed by changing the polarity of either the armature coil or the field coil.
When using the emergency bandage what should you do once the elastic is placed the pressure bar?
reverse the wrapping direction, and continue bandaging the wound
