A circuit with no available path for current flow is
open
An abnormal connection of relatively low resistance between two points in a circuit is a/an
short
The algebraic sum of the voltages around a closed electrical circuit must equal zero
Kirchoff's Law
The voltage derived from Ohm's law is
I x R
The difference of voltage at two terminals of a component having opposition to current flow is
voltage drop
A circuit with only one available path for current flow
series circuit
Total resistance in a series circuit is equal to
the sum of individual resistors in the circuit
If one resistor is increased in value, the voltage drop across it will
increase
If one resistor is decreased in value, the voltage drop across it will
decrease
The total resistance in a series circuit is
the sum of all the resistors
Et=
E1+E2+E3
Rt=
R1+R2+R3
It=
I1=I2=I3
The sum of the individual voltage drops in a circuit is equal to the
total voltage
The voltage drop across a shorted component is equal to
zero
The voltage drop across an open component is equal to
the source voltage
What happens to the total power if a component is shorted?
it increases
What happens to the total power if a component is open?
total power is zero
An ohmmeter should be connected to a series circuit only if
the circuit is off
An ammeter is connected
in series
If one component in a series circuit shorts, the total current would
increase
