Basic Electricity Flashcards
The number of millivolts in one volt is
1000
Most transformers in hvac are reduced to what voltage
24v
To decrease the resistance in an electrical circuit you must
Increase the wire size
Possibly run parallel circuit..
The term continuity testing means:
Proving a continuous conducting path in an electrical circuit
When checking a 24v circuit for continuity with an ohm meter , you must ?
Disconect the power source from circuit
Most heating and cooling safety controls are
Series circuits
An iron core inserted into a coil will cause the magnetic field to?
Increase
The resistance of the wiring in a circuit
Decreases with an increase in wire diameter
The unit used to measure resistance is a
Ohm
A solenoid valve, with an open coil would indicate what condition during a continuity check
OL no continuity
High resistance
Infinite resistance
Electrical energy is produced when electrons are
Freed from their atoms
The force that causes the electrons to flow through the conductor is measured in?
Volts = Electromotor force
The flow through a conductor of fixed resistance can be increased by increasing the?
Voltage
One amp will flow through a resistance of one ohm when it is forced by?
One volt = force
Symbol for voltage
E
