In a series circuit, which of the following is the same across all branches of the circuit?
conductance |
|
resistance |
|
voltage |
|
current |
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.
You would measure the amount of current through a circuit with a(n):
ammeter |
|
potentiometer |
|
voltmeter |
|
battery |
Current is the rate of flow of electrons per unit time and is measured in amperes (A). An ammeter is used to measure the electric current in a circuit.
A transistor to an electronic circuit is like a _______________ to a house?
gate |
|
driveway |
|
no trespassing sign |
|
safe |
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.
The sum of the voltage drops across each resistor in a __________ circuit will equal the total voltage applied to the circuit.
series |
|
parallel |
|
series-parallel |
|
closed |

In an electronic circuit, a thermocouple can be used to:
keep the circuit at a designated safe temperature |
|
link the temperature of one component in the circuit to that of another component in the circuit |
|
open or close a circuit at a designated temperature |
|
increase or decrease the temperature of a component in the circuit |
A thermocouple is a temperature sensor that consists of two wires made from different conductors. The junction of these two wires produces a voltage based on the temperature difference between them and can be used like a switch to open or close the circuit at a designated temperature.
