The sum of the voltage drops across each resistor in a __________ circuit will equal the total voltage applied to the circuit.
series |
|
closed |
|
series-parallel |
|
parallel |
A series circuit has only one path for current to flow. In a series circuit, current (I) is the same throughout the circuit and is equal to the total voltage (V) applied to the circuit divided by the total resistance (R) of the loads in the circuit. The sum of the voltage drops across each resistor in the circuit will equal the total voltage applied to the circuit.
A transistor to an electronic circuit is like a _______________ to a house?
driveway |
|
no trespassing sign |
|
safe |
|
gate |
A transistor works by allowing a small amount of current applied at the base to control general current flow from collector to emitter through the transistor. A transistor acts as a gate or switch for electronic signals.
What is the voltage of most household electrical systems in the United States?
60V |
|
220V |
|
110V |
|
60Hz |
Most households use electricity with a voltage of 110V.
Which of the following statements about electrical resistance is true?
electrically conductive materials have no resistive properties |
|
the less resistive the conductor is the slower electron flow will be |
|
the more resistive the conductor is the slower electron flow will be |
|
the more resistive the conductor is the faster electron flow will be |
Resistance is opposition to the flow of current. As resistance increases, current decreases as resistance and current are inversely proportional.
The joule is a unit of measurement for:
resistance |
|
energy |
|
capacitance |
|
power |
The joule is a unit of measurement for energy.
