Read the given passage and answer the questions asked.
When you start an experiment connected to a meter bridge you need a galvanometer and a resistance box. Meter bridge is a device which works on the principle of Wheatstone and with the help of it we can find the resistance and specific resistance of a given wire. Meter bridge has a long magnin wire whose length is 1 meter, its length can be less than or more than 1 meter. While using a meter bridge, first of all we should press the key connected to the cell and then press the key connected to the galvanometer.
1-Is the length of meter bridge wire fixed at 1 meter?
2-On what principle does meter bridge work?
3-Can we also find the specific resistance with the help of meter bridge? If yes then how?
4-Why should we not first press the key connected to the galvanometer?
5-What accessories are required in the experiment related to meter bridge?
