| DC motors with permanent magnets are widely used and popular among model builders. A particular characteristic of these motors is a large di...
| Measurements in digital circuits fall into two categories: (1) voltage, current and resistance; and (2) data. The first category presents...
| The test methods described so far in this series apply only to low-frequeney (LF) equipment. In circuits carrying high-frequency (HF) sig...
| If a circuit ceases to function and it shows no visible damage, a voltage analysis should be the first step in locating the fault. Voltage...
| Audio-frequency technology is of particular interest to many electronics enthusiasts since it seems to surround us in our everyday life in...
| This month's instalment deals with a very important measurement: that of resistance. This measurement is important not only in faultfindin...
| Following the discussion in our previous issue on the measurement of voltage, this month's instalment deals with the measurement of curren...
| After the brief discussion on measuring, errors and tolerances, we now turn our attention to practical measurements, more particularly the...
| Three-phase motors, particularly asynchronous types, are very reliable and consequently popular prime movers. A drawback of these engines...
