Current and Resistance. Chapter 27. Electric Current. Flow of electric charges through a piece of material Amount of flow depends on material and the potential difference across the material Whenever there is a net flow of charge through a region= there is an electric current.By elan

Called?. Resilience and Personal Vocation in Education Dr Nick Shepherd Programme Director for Setting God’s People Free (yes that’s a real job title - it’s on my business card and everything). Setting God’s People Free. celebrating and affirming calling for all….
CALLED. Called to walk before God as willing and faithful servants… as Abraham was called to a new place and to trust in the Lord. Called to go God’s Way, not our own… “The Way” is Jesus Christ, and we are called to go in… along… on… “The Way”.
RESISTANCE. RESISTANCE. Ohm – Unit for resistance Circular Wires Circular mils 1000 mils = 1 inch. RESISTANCE. Malleability- property of a metal to be deformed by compression without cracking or rupturing.
Resistance. Challenge. Try and increase the temperature of 200 ml of tap water as much as possible in five minutes using the equipment provided. Looking down into an electric jug. Some examples of incandescent lights.
Resistance. and resistivity. Current. Current is sort of a vector Direction is constrained by conductor Restricted to forward or backward (+ or –). Resistance. Current does not flow unhindered Electrical resistance is analogous to friction or drag
Resistance. Antibiotics. What type of organism do they target? Bacteria What do they do to be effective ? Control Growth Kill bacteria When aren’t they effective? Viruses – use antivirals. Spectrums. Wide-spectrum Can target many different kinds of bacteria . Narrow-spectrum
Low at high frequency. Low at low frequency. Ω. Ω. f. f. Resistance. Impedance. Energy Storage. DC Direct Current. AC Alternating Current. Electric Field Capacitance. Magnetic Field Inductance. Resistor R Ohms. Reactance Z Ohms. Inductor L Henry. Capacitor C Farad.
Resistance. Electrostatic interaction. Fluid friction. A constant force leads to a constant current. No voltage. I=0. Higher voltage. F. I. Higest voltage. Resistance (2). No voltage. I=0. Voltage. F. I. U. Capacitor. +. +. I. -I. U. U. An „analogy“ to capacitor.
Resistance. Lesson 11. Resistance. The degree to which a substance opposes the flow of electric current through it. All substances resist electron flow to some extent. . Resistance. Conductors, such as metals, allow electrons to flow freely through them and have low resistance values.
