Current Electricity. An electrical current is a flow of charged particles (electrons or ions) through a circuit.
Ohm’s Law Calculating Current, Voltage, and Resistance.
P = V I (1a) P = R I 2 (1b) P = V 2 / R (1c) where P = power (Watts) V = voltage (Volts)voltage I = current (Amperes) R = resistance (Ohms)
The “Live Action” Physics Review Game Topic: Circuits.
Measurements in Electric Circuits Gr. 9 Electricity Unit.
ELECTRIC CURRENT Electricity, like water, can only flow if charged particles have potential.
Ohm’s Law Aim: How does voltage and resistance affect current flow?
Electricity and Circuit. Types of Electricity Static Electricity – no motion of free charges Current Electricity – motion of free charges – Direct Current.
In the last chapter we examined how static electric charges interact with one another. These fixed electrical charges are not the same as the electricity.
CURRENT ELECTRICITY Characteristics of Current Electricity.
Circuits & Electronics. Ohm’s Law When you connect a conductor (wire) and a device (light bulb) to the + and – terminals on a battery an electrical current.
Current Resistance Electric Power & Energy. Voltage (V) Electric potential difference between 2 points on a conductor Sometimes described as “electric.
Electrical Resistance Electrical resistance is a measure of how difficult it is for electricity (electrons) to flow through a material. The units of resistance.

IMPORTANT ELECTRONIC TERMS. Voltage "V" A measure of electrical potential, it is measured in volts A measure of the pressure under which electricity flows.
Rate (how fast) at which charges pass a given point Measured in Amperes or amps Current (I) Electrons moving in a wire make up current and provide.
Unfortunate book names:. A circuit must contain a source of potential difference, and a path for the flow of charge. It will probably also contain.

What is Electricity? Electricity is the flow of moving electrons. When the electrons flow it is called an electrical current.
The continuous flow of electrons is current. Measured in amps (A). Two types of current 1. Direct current (DC) – electrons flow in only one direction.
Welcome to Physics Jeopardy Chapter 18 Final Jeopardy Question Equivalent Resistance 100 Complex circuits Misc Parallel.
a path along which electrons flow must have no breaks in the path to work 2 types: –closed (no breaks) –open (break, causes the device to shut off - switch)
The flow of charged particles charged particles ; through a conducting metal.
Electricity on the Move. Current Electricity Unlike static electricity, which does not move except when discharged, current electricity is a continuous.
