what is a control circuit
A control circuit is an circuit that controls some major load in a system
parallel circuits are used in the air-conditioning industry to ____
A. Supply the correct line voltage to several circuits.
what is a series-parallel circuit
A. combination circuit made of series and parallel.
what is a parallel circuit
An electric circuit that has more than one path for current flow.
the voltage drop of a series circuit is ____
B. Proportional to the resistance in that part of the circuit
the current draw in a series circuit is ____
B. The same throughout the entire circuit.
if two 115 volts loads were connected in parallel with 240 volts they would ____
C. burn correctly
two 115 volt loads connected in series with 240 volts would
C. burn correctly
why are series-parallel circuit important in the circuitry used in air-conditioning equipment
In control circuitry, safety and operating controls must be wired in series while most loads must receive line voltage and must be wired in parallel
how would switches used as safety device be connected with respect to the load they are protecting
In series
how are series circuit used for most control circuits
To operate the equipment and maintain a desired temperature
why are series circuits used in air-conditioning equipment
To stop the function for safety and control.
what is a series circuit
an electrical circuit that has only one path for electron flow
safety devices in an electrical circuit are connected in ____ with the load
sears
draw a series-parallel circuit with one switch () controlling two electric heaters, each being supplied with line voltage
switch open
why are parallel circuits used in the air-conditioning industry
to supply line voltage loads in equipment or a control circuit
true or false: the current draw of a parallel circuit is the sum of the current of each branch
true
