A circular of 500 turns of wire has anclosed area of 0.1m^(2) per turn. It is kept perpendicular to a magnetic field of induction 0.2T and rotated by 180^(@) about a diameter perpendicular to the field in 0.1s. How much charge will pass when the coil is connected to a galvanometer with a combined resistance of 50 Omega. |

Answer» SOLUTION :Charge `= ("charge in FLUX")/("resistance")` `q= (phi_(i) - phi_(f))/(R )= (NBA- (-NBA))/(R )= (2NBA)/(R )` `q= (2 XX 500 xx 0.2 xx 0.1)/(50)= 0.4C` |
