Connecting the 6 batteries in series multiplies their voltage while keeping their current the same yielding a 72V 20A configuration. Connecting the 6 batteries in parallel multiplies their current while keeping their voltage the same yieleding a 12V 120A configuration. Using a series-parallel connection, 3 batteries can be connected in series and 3 can be connected in parallel resulting in a 36V 60A configuration.
Current is the rate of flow of electrons per unit time and is measured in:
coulombs |
|
amperes |
|
volts |
|
ohms |
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 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.
The valence shell of a semiconductor is how full of electrons?
less than half full |
|
empty |
|
more than half full |
|
half full |
Semiconductors have valence shells that are exacly half full and can conduct electricity under some conditions but not others. This property makes them useful for the control of electrical current.
This circuit diagram represents a(n):
series circuit |
|
open circuit |
|
parallel 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.
