WebThe galvanometer shows the direction of current flows in the circuit whereas the ammeter measures the magnitude of current flows through it. The magnetic field is required for the working of galvanometer whereas it is not essential for the ammeter. The accuracy of the galvanometer is less as compared to the ammeter. WebSep 11, 2024 · The galvanometer shows a momentary deflection when the tapping key K is pressed. If the key is held pressed continuously, there is no deflection in the galvanometer. When the key is released, a momentory deflection is observed again, but in the opposite direction.

There are tools that can be used to draw vectors and label them. Vectors and labels can be clicked and dragged onto the screen at any time. The arrows can be adjusted by clicking on the WebThis is the bridge balance condition. Only under this condition, galvanometer shows null deflection. Suppose we know the values of two adjacent resistances, the other two resistances can be compared. If three of the resistances are known, the value of unknown resistance (fourth one) can be determined. EXAMPLE 2.23
