The potential energy per unit measure is called? A) electric field B) electric potential C)potential energy
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
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.
Electric Current. Electric Potential Electrons in a circuit have potential energy –The energy is related to the force exerted by an electric field –The.
2c) Energy and Potential Difference in Circuits Part 1 Current and Charge.
Electric Current and Electrical Energy Current Electric current is the rate at which charges pass a given point An electric current can be made.
Current and 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.
