How do you write a meter bridge experiment?
Measure the distance of terminal point C of the meter bridge from the balancing point (where the galvanometer showed zero deflection). This length is ‘l2’. Compute the average length ‘l’ of l1 and l2 using the formula: (l1 + l2)/2. Repeat the whole experiment for a few more values of R.
What is the formula for meter bridge?
ρ=Lπr2X ; Where L be the length of the wire and r be its radius.
What is metre bridge experiment?
A metre bridge, also known as slide wire bridge is an instrument that works on the principle of Wheatstone bridge. It is used to determine the unknown resistance of a conductor. Below is an experiment on how to find the resistance of a given wire using metre bridge and to determine the resistivity of its material.
What is a meter bridge?
A meter bridge also called a slide wire bridge is an instrument that works on the principle of a Wheatstone bridge. A meter bridge is used in finding the unknown resistance of a conductor as that of in a Wheatstone bridge.
What is meter bridge Ncert?
Metre bridge, a wire about 1m long (of material whose specific resistance is to be determined), a resistance box, a rheostat, galvanometer, a jockey, one-way key, a cell or battery eliminator, thick connecting wires, sand paper, screw gauge.
Why is meter bridge called so?
The reason why this bridge is called the Meter Bridge is because of the fact that it works on the Wheatstone bridge’s principle. So, people also popularly call it Wheatstone’s meter bridge. Another thing is that the wire length used in this circuit is 1 meter, so it has got its name as a meter bridge.
Metre Bridge Experiment with Readings (Class 12) METRE BRIDGE EXPERIMENT – I. Aim: To find the resistance and hence determine the resistivity of the material of the wire. Apparatus: Metre bridge, Battery (E), Key (K), Resistance box (R), Given resistance wire (X), High resistance (HR), Galvanometer (G), Jockey (J), Screw gauge etc. Principle:
How to find resistance of a given wire using metre bridge?
To find resistance of a given wire using metre bridge and hence determine the resistivity (specific resistance) of its material. Metre bridge apparatus is also known as a slide wire bridge. It is fixed on the wooden block and consists of a long wire with a uniform cross-sectional area.
What is a a meter bridge used for?
A metre bridge, also known as slide wire bridge is an instrument that works on the principle of Wheatstone bridge. It is used to determine the unknown resistance of a conductor.
What is the length of a meter bridge wire?
In the meter bridge, one of the lateral kinds of resistances is replaced by a wire having a length of the uniform cross section of about 1m. The other pair consists of one known and an unknown pair of resistances.
