Dynamic Characteristics: Instruments rarely respond instantaneously to changes in the measured variables. Instead, they exhibit slowness or sluggishness due to such things as mass, thermal capacitance, fluid capacitance or electric capacitance. In addition to this,…
Dynamic Braking of Induction Motor(or Rheostatic Braking): (a) AC Dynamic Braking - AC Dynamic Braking of Induction Motor is obtained when the motor is run on a single phase supply by disconnecting one phase from…
Duty Cycle of Traction Drives: The Duty Cycle of Traction Drives in trains is explained with the help of speed-, torque- and power-time diagrams (Fig. 10.6) which are drawn for travel between two consecutive stations…
Duties of circuit breaker diagram: Under different circumstances Duties of circuit breaker diagram may be subjected to widely varying stresses. First of all the current varies from a few amperes due to no-load current of…
Dual Trace Oscilloscope: Figure 7.19 (a) shows a block diagram of Dual Trace Oscilloscope. This CRO has a single electron gun whose electron beam is split into two by an electronic switch. There is one…
Dual Slope Integrating Type DVM (Voltage to Time Conversion): Dual Slope Integrating Type DVM - In ramp techniques, superimposed noise can cause large errors. In the dual ramp technique, noise is averaged out by the…
Dual Input Unbalanced Output Differential Amplifier: It is an important configuration and converts dual inputs into a single ended output. In this configuration, two input signals are applied and the output is measured at only…
Dual Input Balanced Output Differential Amplifier: The dual input balanced output differential amplifier configuÂration is shown in Fig. 20.2. In the given circuit two input signals vin1 and vin2Â are applied to the bases B1 and…
Dual Gate MOSFET - N Channel Depletion Type MOSFET: Cross view of a dual-gate N-channel depletion type MOSFET is shown in Fig. 13.93. It acts as if two FETs are connected in series, as is…
Dual Converter Control of DC Separately Excited Motor: A Dual Converter Control of DC Separately Excited Motor (Fig. 5.35) consists of two fully-controlled rectifiers connected in anti-parallel across the armature. For power ratings upto around…
