Ohm's Law
V/R
A
The pressure from an electrical circuit's power source that pushes charged electrons (current) through a conducting loop
What is Voltage
A path along which the whole current flows through each component
What is a Series Circuit
Power systems that use only one polarity of voltage or current
What is direct current DC Voltage
What is the current flowing through a hair dryer if it is plugged into a 120-volt circuit which has a resistance of 5 ohms?
What is 24 amps
A x R
V
A unit of power
What is a Watt
A path that increase the amperage as electrons flow though.
What is a Parallel Circuit
A resistance to current that illuminates
What is a light bulb
An alarm clock draws 1.5 A of current when connected to a 110-volt circuit. What is the resistance?
What is 73.3 ohm's
Voltage goes up amperage goes
Up
A measure of the opposition to current flow in an electrical circuit
What is Resistance
Comprises branches so that the current divides and only part of it flows through any branch.
What is a Parallel Circuit
An electric current which periodically reverses direction and changes its magnitude continuously
What is Alternating Current (AC)
An electric heater works by passing a current of 105 amps. If the resistance of the wire is 0.5 ohms, what is the voltage?
What is 52.5 V
V/A
R
What is an Electron
One bulb can cause a complete system failure.
Series Circuit
Some thing that uses current
What is an Electrical load
A circuit contains a 12-volt battery and a bulb with a resistance of 3 ohms. Calculate the current
What is 4 amps
Current goes down
Resistance goes up
The strength of an electric current
What is Amperage
When voltage drops over the entire circuit
What is a Series Circuit
opens or closes a circuit
What is a switch
P=VxA
What is Watts law
