Q: 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
,Q: If voltage is constant, what could cause current to increase?
Answer:
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 (T/F) Current will be the same throughout the series
circuit? 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
, Q: If a circuit is wired so that electrons can flow in only one possible path, the
circuit is said to be
Answer:
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
The total current in a parallel circuit will be: The sum of the current passing through
each
branch of the circuit
(T/F) The total resistance of the circuit will be less than the smallest resistance in the
circuit for
a parallel circuit True
(T/F) A corroded switch will not cause a parallel circuit to act like a series-parallel
False
Given a constant supply, the current through each branch circuit in a parallel circuit
depends
on.. The resistance of the load in that branch circuit
Which type of circuit will allow a load to deliver its design power rating if the load is
designed
for 24V? 24V parallel circuit- No matter which branch line it is installed in
In North America, AC power is produced at a frequency of ___ cycles per second
(also known as
___ hertz) 60
Back emf is an electrical term that means: Induced voltage from the coil of an
inductor that
opposes applied voltage
