In a series circuit, which of the following is the same across all branches of the circuit?
conductance |
|
voltage |
|
current |
|
resistance |
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 ampere is a unit of measurement for:
energy |
|
power |
|
inductance |
|
current |
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.
The hertz is a unit of measurement for:
power |
|
inductance |
|
energy |
|
frequency |
The hertz is a unit of measurement for frequency.
Longer the electrical wires mean _______________ voltage drop.
lesser |
|
complete |
|
diminishing |
|
greater |
Electrical wires have a certain amount of resistance per foot. A longer wire means more resistance and a greater voltage drop.
The diameter of a number 12 wire is __________ the diameter of a number 6 wire?
less than |
|
double |
|
triple |
|
more than |
The larger the number the smaller the diameter of the wire. So, the diameter of a number 12 wire is less than the diameter of a number 6 wire.
