Question
Download Solution PDFA moving coil of a meter has 100 turns and a length and depth of 10 mm and 20 mm respectively. It is positioned in a uniform redial flux density of 200 mT. The coil carries a current of 50 mA. The torque on the coil is
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFConcept:
In PMMC meters deflecting torque is given by,
\({T_d} = BINA\)
B is the magnetic flux density
I is the current
N is the number of turns
A is the area of cross section
Calculation:
\({T_d} = 200 \times {10^{ - 3}} \times 100 \times 10 \times {10^{ - 3}} \times 20 \times {10^{ - 3}} \times 50 \times {10^{ - 3}}\)
\({T_d} = 200\;\mu \;N - m\)
