Q. Match the area A of the quadrilateral with their diagonal d cm & the sum of their heights $(h_1+h_2)$ cm.

Q. A moving coil galvanometer has a resistance of $9.8\Omega$ and gives a full scale deflection when a current of $10mA$ passes through it. The value of the shunt required to convert it into a milliammeter to measure current upto $500mA$ is

Q. A galvanometer of resistance $100\Omega$ gives full scale deflection at $10mA$ current. What should be the value of shunt so that it can measure a current of $100mA$?
