SAS Lecture 6 – SAS/GRAPH. Aidan McDermott, May 3, 2005. SAS/GRAPH. There are a small number of graphic types commonly used in public health presentations and publication. These basic types are either used alone or mixed together to form a composite graphic.By burton

CURRENT SOURCES, CURRENT SINKS AND CURRENT MIRRORS. CURRENT SINKS AND SOURCES Characterization of Current Sinks and Sources: Minimum voltage (V MIN ) across sink or source for which the current is no longer constant.
Chapter 21. Current and Direct Current Circuits (+Alternating Current). A.C. Versus D.C. Study Note. No need to memorize any equations in this file. This is just a qualitative introduction to alternating current ( a.c .). Alternating Current. Voltage and Current. US: 120V rms, 60Hz
Chapter 5. Current and Conductors. Current and Current Density. Electric charges in motion constitute a current . The unit of current is the ampere (A), defined as a rate of movement of charge passing a given reference point (or crossing a given reference plane).
Alternating Current Direct Current. Components of Electrical System. Voltage source = generator/batteries Conductor = wires Control Element = switch Load = light bulb, motors, appliances. Alternating Current. Electrons flow back and forth 60 times per second
Current. “You’ll get a charge out of this”. Current is measured in Amperes (amps or A). 1 amp = rate of flow such that 1C of charge moves past a point in 1 second. or. q = charge (C) I = current (A) T = time (s). If 1.6 C moves past a point in 1.2s, what is the current?. Work Done
Comment on neutron yield from BeCu dump. RadCon heard we have a new BeCu dump. make sure it was documented (done) survey it (explained not possible) They tell us we are making neutrons. Yield is “small” C oncerned we activated Pb bricks Agreed if Pb doesn’t help will remove.
POLARITON LIGHT EMITTING DEVICES: RELAXATION DYNAMICS. Dept of Materials Sci. & Tech Microelectronics Group University of Crete / IESL. Simos Tsintzos. Polariton emitter. Top Mirror. Active region. Current. Bottom Mirror. Polariton Physics at Crete.
Current. A charge in an electric field is subject to a force. Acceleration Positive charges move with the field. Negative charges move against the field. -. +. Moving Charge. E. Moving water in a pipe forms a current. Steady flow at constant velocity
