This circuit diagram represents a(n):
open circuit |
|
parallel circuit |
|
series circuit |
|
series-parallel circuit |
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.
The sum of the voltage drops across each resistor in a __________ circuit will equal the total voltage applied to the circuit.

The ampere is a unit of measurement for:
current |
|
power |
|
inductance |
|
energy |
Current is the rate of flow of electrons per unit time and is measured in amperes (A). A coulomb (C) is the quantity of electricity conveyed in one second by a current of one ampere.
You would measure the amount of resistance at a certain point in a circuit with a(n):
ohmmeter |
|
potentiometer |
|
voltmeter |
|
ammeter |
Resistance is opposition to the flow of current and is measured in ohms (Ω). An ohmmeter is used to measure the amount of resistance at a certain point in a circuit.
What is the frequency of most household electrical systems?
110V |
|
60MHz |
|
60Hz |
|
110Hz |
Electricity is delivered from power stations to customers as AC because it provides a more efficient way to transport electricity over long distances. Most households use electricity with a frequency of 60Hz.
