An ammeter has a f.s.d. of 100 mA and a resistance of 5022. The ammeter is used to meas- ure the current in a load of resistance 500 2 when the supply voltage is 10V. Calculate (a) the ammeter read- ing expected (neglecting its resistance), (b) the actual current in the circuit, (c) the power dissipated in the ammeter, and (d) the power dissipated in the load. From Figure 10.10, 0-100 mA A ra = 50 Ω R = 500 02 10V
