Deflection in magnetometer along -axis of coil. Conversion of Galvanometer to Ammeter Object: The value of R is determined by following expression. Table for value of P and Q for Ist capacitor Sr. Connections should be tight.

Let us mark the current drop across unknown capacitor as e 1voltage drop across the resistor r 3 be e 3voltage drop across arm be e 4 and voltage drop across arm be e 2. Distance Micrometer reading cm No. What is the SI unit of pressure? If there is found a range of no deflection then total range should be noted and mean of them should be taken for R at no deflection.

All the uprights should be exactly at same height and at same horizontal axis. On solving above equation we get: Figure and Circuit Diagram Observations. Circuit diagram of De-Sauty Bridge Observation: Variation in voltage should be in slow manner. Answer to this question is very simple as capacitor is connected there, therefore phase difference angle obtained is 90 o.

## 1. DE-SAUTY BRIDGE

Ver At minimum deviation Direct Colour No. Now instead of some advantages like bridge is quite simple and provides easy calculations, there are some disadvantages of this bridge because this bridge give inaccurate results for imperfect capacitor here imperfect means capacitors which not free from dielectric losses. Key K2 should be always pressed after pressing key K1.

Table for angle of 1st order diffraction Telescope reading for reflection Sr. What is the unit of G in S.

LHS zauty cm No. Also he has connected resistances R 1 and R 2 respectively in the arms and Let us derive the expression capacitor c 1 whose value is unknown to us. Science Physics Electronics 1.

## De Sauty Bridge

At balance condition the current flows through path will be zero and also voltage drops e 1 and e 3 be equal to voltage drops e 2 and e 4 respectively. Inductive reactance, X C: To convert Weston galvanometer to btidge ammeter of current range 0 to 1. Can a dissipation factor be measured by De Sauty’s bridge? D EV Circuit Diagram: Lenses should be of small aperture to get well defined and sharp image.

Thus the length of shunt wire required for converting the given galvanometer in to ammeter of range 0 to 1. This the required equation.

This modification is done by Grover. Again we connected standard capacitor on the same arm as we have done in De Sauty’s bridge. Hence we can use this bridge only for comparing perfect capacitors. What are the C. Connections should not be loose. At balance point on equating the voltage drops we have: What are the advantages that Carey Foster method has compared to simple meter bridge for measuring resistance? Voltmeter should be connected using sign convention.

The feedback you provide will help us show you more relevant content in the future. However this method is gives quite inaccurate results for dissipation factor.

### De Sauty Bridge

For first position No. Learn More at wikibuy.

The resistances should be high. Why is Wheatstone bridge not used to measure low resistance? If a current carrying coil is place in y-z plane then its axis will be x-axis.

Avoid pressing keys for large time otherwise cell will be discharged. What is the SI unit of density? What is the I. S unit of heat? The current should remain constant and should be reversed for each observation. The cross slit must be properly illuminated by the intense light coming from lamp. Movement in galvanometer should be free.

For angle of prism Observation: The following formula is used for the determination of galvanometer resistance.
