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

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

Science practical report (The relationship between voltage and Current) Aim: To find out how current‚ voltage and résistance in a electric circuit are related. Hypothesis The reading for both voltmeter and ammeter will have complete different results in relationship to the resistor‚ voltage and current. That voltmeter will have a higher reading than ammeter. Materials * Power pack * Piece of nidrome * 50 cm long or a resistor * Hear proof mat * 6 connecting wires *

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

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

Activity 8: Nerve Conduction Velocity • In this activity‚ we will be investigating action potential like in activities 1-4‚ and the nerve conduction velocity. We will test an earthworm nerve‚ frog nerve‚ and two rat nerves on the oscillator. The factors that helped determine action potential were the Bio-amplifier‚ stimulator‚ ethanol‚ and voltage. C.
