Connecting the 10 batteries in series multiplies their voltage while keeping their current the same yielding a 60V 10A configuration. Connecting the 10 batteries in parallel multiplies their current while keeping their voltage the same yieleding a 6V 100A configuration. Using a series-parallel connection, 5 batteries can be connected in series and 5 can be connected in parallel resulting in a 30V 50A configuration.
A diode to an electronic circuit is like a _______________ to a city?
parking lot |
|
highway |
|
traffic light |
|
one-way street |
A diode allows current to pass easily in one direction and blocks current in the other direction.
Electrons will flow as current from areas of __________ potential (concentration of electrons) to areas of __________ potential.
low, low |
|
low, high |
|
high, high |
|
high, low |
Voltage (V) is the electrical potential difference between two points. Electrons will flow as current from areas of high potential (concentration of electrons) to areas of low potential. Voltage and current are directly proportional in that the higher the voltage applied to a conductor the higher the current that will result.
Which of the following will increase the magnetic field produced by the electric current in a wire?
construct the wire from insulative material |
|
wrap the wire around a ceramic core |
|
construct the wire from conductive material |
|
wind the wire into a coil |
A moving electric current produces a magnetic field proportional to the amount of current flow. This magnetic field can be made stronger by winding the wire into a coil and further enhanced if done around an iron containing (ferrous) core.
This circuit component symbol represents a(n):
inductor |
|
diode |
|
capacitor |
|
transistor |
A diode allows current to pass easily in one direction and blocks current in the other direction. Diodes are commonly used for rectification which is the conversion of alternating current (AC) into direct current (DC). Because a diode only allows current flow in one direction, it will pass either the upper or lower half of AC waves (half-wave rectification) creating pulsating DC. Multiple diodes can be connected together to utilize both halves of the AC signal in full-wave rectification.
