An ammeter has a f.s.d. of 100 mA and a resistance of 50 2. The ammeter is used to meas- ure the current in a load of resistance 500 when the supply voltage is 10 V. 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, Figure 10.10 0-100 mA A Ta = 50 Ω = R=500 Ω R= 10V
