An ammeter has a f.s.d. of 100 mA and a resistance of 50 ohm. The ammeter is used to measure the current in a load of resistance 500 ohm when the supply voltage is 10V. Calculate the ammeter reading expected (neglecting its resistance), the actual current in the circuit, the power dissipated in the ammeter, and the power dissipated in the load.
