Ohm's Law
This law describes the relationship between voltage, current, and resistance in an electrical circuit?
Ohm’s Law
In this type of circuit, all components share one path for electricity.
a series circuit
The unit used to measure electrical power.
watts
Like magnetic poles do this to each other.
repel
This type of current flows in only one direction.
direct current (DC)
If voltage increases and resistance stays the same, this happens to current.
current increases
In this type of circuit, components are connected on separate branches.
a parallel circuit
This device measures electrical energy used in a home.
electric meter (kWh meter)
Unlike magnetic poles do this to each other
attract
This type of current changes direction and can travel long distances easily
alternating current (AC)
The formula used to calculate current using power and voltage.
I = W / V
In a series circuit, adding more devices causes this to happen to total resistance.
resistance increases
Power depends on these two quantities in the equation P = IV
current and voltage
This metal is strongly attracted to magnets.
iron
This device transfers electrical energy between circuits using electromagnetic induction.
transformer
If resistance increases while voltage stays constant, this happens to the current.
current decreases
This happens in a circuit when electricity takes a path with almost no resistance.
short circuit
A safety connection that sends extra electricity safely into the Earth.
grounding
The region around a magnet where magnetic forces act.
magnetic field
Electromagnets can do this unlike permanent magnets.
be turned on and off
The unit used to measure electrical current.
amperes (amps)
A device like a fan or lightbulb in a circuit that uses electrical energy.
a resistor (or load)
If your body is wet, this level of voltage can be fatal
about 100 volts
The process of making an object magnetic using another magnet.
magnetic induction
The historical competition between AC and DC power systems
