Q: number, the thicker the wire.
Answer:
(T/F) A junction box connector approved for the box and wire type must be used
True
The ohmmeter reading across a good fuse that is removed from the circuit, will be: 0
The ohmmeter reading across a blown fuse that is removed from the circuit, will be:
Infinity
A badly burned or charred fuse indicates: A short circuit
(T/F) A voltage drop never occurs across a switch False
,Q: The line connection terminals on a 120-volt receptacle are: Gold The neutral
connection terminals on a 120-volt receptacle are: Silver Ohm's law states: It
takes one volt to push one amp through one ohm If voltage is increased in a
simple circuit, current will: Increase Given a constant supply voltage, if
resistance increases in a simple circuit, current will: Decrease Electrical power is
measured in units of: Watts One horsepower of mechanical power is equal to
___ watts of electrical power 746 Which of the following changes to an
electrical circuit will increase power delivery to the load?
Answer:
Current can increase, resistance can decrease, and voltage can increase If voltage is
constant, what could cause current to increase? A decrease in resistance One watt
equals ____ Btuh 3.41 What is the btuh output of an electric heater rated at 20 kW?
68,240 If one load fails in a series circuit, then: All the loads would stop working
, Q: (T/F) Current will be the same throughout the series circuit?
Answer:
True With constant supply voltage, what will be the effect on total current if the
resistance is decreased in any one branch circuit of a parallel circuit? Amperage will
increase The total resistance of a series circuit that consists of two 10 ohm loads is:
20 ohms The amperage reading at any point in a parallel circuit will be: Different on
the main line compared to each branch line If the voltage drop across a load in a
simple circuit is not the applied voltage, this indicates: There is more than one load
wired in series with the tested load The equivalent resistance of two 20 W resistors
connected in parallel is: 10 W The equivalent resistance of two 20 W resistors
connected in series is: 40 W The current required to operate a device rated for 1200
watts at 120 volts is: 10 amps If a circuit is wired so that electrons can flow in only
one possible path, the circuit is said to be a/an: series circuit In a parallel circuit
containing a 10 W, a 20 W, and a 30 W resistor, the current flow is: Highest through
the 10 W resistor Total resistance in a series circuit is equal to: Sum of each
individual resistance in the circuit
