Why shunt resistance is connected in the parallel?
Shunt means parallel only..................
Is shunt a bypass resistance?
It is the resistance across the cell to invoke a constant draw. This makes the cell work efficiently under ideal conditions. To do it properly new cell management systems measure the temp. and voltage output and put a load on the cell that makes it work best.
What is the reason of connecting shunt parallel to galvanometer?
to reduce the flow of current & keeping the current through galvanometer within safe limits.
What are the differences of Long shunt vs short shunt generator?
In long shunt the shunt field winding is in parallel to both generator and series field. In short shunt the shunt field is in parallel to generator only.
How will a shunt generator behave if the field resistance is greater than the critical resistance?
the shunt generator wont be started .hehe
What kind of meter is created when is shunt is added to a galvanometer?
A galvanometer with a low resistance shunt in parallel makes an ammeter.
How you convert galvanometer into ammeter in detail?
By attaching a resistance in parallel connection with the galvanometer. Or when a low resistor connected in parallel with galvanometer ,the galvanometer is converted in ammeter. and the resistor is called shunt resistance.
Why shunt resistance is used ammeter?
A shunt resistance is a low resistance connected parallel to the galvanometer so that a large portion of current passes through the low resistance and a small fraction of current passes through the galvanometer this saves the galvanometer from damage
How can you convert galvanometer into ammeter?
Since Galvanometer is a very sensitive instrument therefore it can't measure heavy currents. In order to convert a Galvanometer into an Ammeter, a very low resistance known as "shunt" resistance is connected in parallel to Galvanometer. Value of shunt is so adjusted that most of the current passes through the shunt. In this way a Galvanometer is converted into Ammeter and can measure heavy currents without fully deflected.

How does a series circuit work with an ammeter?
Actually ammeter is a galvanometer which is shunted by a resistance called shunt. For large currents major part of it is bypassed through the shunt. The parallel combination of shunt resistance and meter resistance is added to the circuit resistances , so the value indicated by the ammeter is slightly lesser than the actually value.
How do you convert galvanometer to an ohmmeter?
"An ohmmeter is an electrical instrument that measures electrical resistance, the opposition to an electric current."The unit of measurement for resistance is ohms (Ω).It is useful device for rapid measurement of resistance. It is consist of galvanometer and adjustable resistance Rs of known value and a cell connected in series. The resistance R to be measured is connected between the terminals.The series resistance Rs is so adjusted that when the terminals are short circuited i.e., when R = 0, the galvanometer gives full scale deflection. So the extreme graduation of the usual scale the galvanometer is marked 0 for resistance measurement. When terminals are not joined no current passes through the galvanometer and its deflection will be zero . Thus zero of the scale marked as infinity. . When R is not infinite , the galvanometer deflects to some intermediate point depending on the value of R scale can be calibrated to read the resistance directly.

Why shunt resistance used in ammeter and why is it connected in parallel?
An ammeter's coil requires very little current for full-scale deflection (fsd). So, to measure a current above its fsd value, most of that current must be allowed to bypass the coil. This is achieved by placing a very low value shunt resistance in parallel with the coil ('shunt' is an archaic word for 'parallel').
What are the differences of Long shunt vs short shunt generator?
In long shunt the shunt field winding is in parallel to both generator and series field. In short shunt the shunt field is in parallel to generator only.
How is a shunt coil installed?
'Shunt' is an archaic term, meaning 'in parallel with'. So a 'shunt coil' is connected 'in parallel' with... With what, of course, depends upon what sort of device you are talking about. For example the field coil of a d.c. shunt-connected motor has its field winding connected in parallel ('shunt') with the supply.
