    of RVDT’s The two induced voltages of the secondary windings‚ V1 and V2‚ vary linearly to the mechanical angle of the rotor‚ : where G is the gain or sensitivity. The second voltage can be reverse determines by: The difference V1 V2 gives a proportional voltage: and the sum of the voltages is a constant : This constant gives the LVDT great stability of the angular information‚ independence of the input voltage or frequency‚ or temperature

    that the average output voltage could be varied by periodically switching the battery voltage on and off for varying intervals. The principal difference between the thyristor-controlled rectifier and the chopper is that in the former the motor current always flows through the supply‚ whereas in the latter‚ the motor current only flows from the supply terminals for part of each cycle. A single-switch chopper using a transistor‚ MOSFET or IGBT can only supply positive voltage and current to a d.c. motor

    NETWORKS Abstract Contingency analysis of a power system is a major activity in power system planning and operation. In general an outage of one transmission line or transformer may lead to over loads in other branches and/or sudden system voltage rise or drop. The traditional approach of security analysis known as exhaustive security analysis involving the simulation of all conceivable contingencies by full AC load flows‚ becomes prohibitively costly in terms of time and computing resources

    input circuit‚ it can be considered to be a form of an electrical amplifier. When using a relay in a dc current‚ diodes are put in across the coil to dissipate energy from the collapsing magnetic field at deactivation‚ which would cause a spike in voltage and damage components if not there. In a single channel mono block amplifier like the one

    Why do electrons (blue dots) move? Draw a diagram of the battery‚ label the flow of electrons. The flow of current (+) is opposite; draw this and note if toward or away from + terminal of the battery. The electrons are moving because of the voltage of the battery. Away from +terminal. 2. What does the Ammeter (on the left) measure? How is this shown in the sim? An ammeter measures amperes or flow of current 3. What role do the “green dots” in the resistor
