35+ Construction Of Metre Bridge Pictures. A rectangular wooden board has three thick copper strips along its three edges. The wire is of one meter length stretched along the side of a meter scale ac.
Give Construction And Working Of Meter Bridge Current Electricity Physics Class 12 from www.nextgurukul.in It is also capable of measuring the dielectric loss of the capacitor in addition to its capacitance value. The wire is of one meter length stretched along the side of a meter scale ac. The bridge operates by placing rx in the circuit, as shown in figure 1, and then adjusting r3 so that all current flows through the arms of the bridge circuit.
When the bridge is balanced, p r = , where p and q are known resistances, q x r is a variable resistance and x is the unknown resistance.
Volumes greater than 1000 l shall be shown in m3. 2.2 operation for construction of bass board. The constructed bridge is tested and demonstrated to find the value of unknown resistance. Generally speaking, bridges can be divided into two categories:
