An engineer who wants to document an electric circuit would create which of the following?
a layout |
|
a matrix |
|
a schematic |
|
a blueprint |
A schematic is the proper name for a drawing of an electric or electronic circuit.
| 54V 5A | |
| 9V 30A | |
| 27V 15A | |
| 54V 30A |
Connecting the 6 batteries in series multiplies their voltage while keeping their current the same yielding a 54V 5A configuration. Connecting the 6 batteries in parallel multiplies their current while keeping their voltage the same yielding a 9V 30A configuration. Using a series-parallel connection, 3 batteries can be connected in series and 3 can be connected in parallel resulting in a 27V 15A configuration.
Electromotive force is another name for:
power |
|
energy |
|
voltage |
|
current |
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 can conduct electricity under some conditions but not others?
conductor |
|
resistor |
|
semiconductor |
|
insulator |
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.
Capacitors connected in series produce __________ capacitance compared to capacitors connected in parallel.
more |
|
the same |
|
no |
|
less |
Capacitors store electricity and are used in circuits as temporary batteries. Capacitors are charged by DC current (AC current passes through a capacitor) and that stored charge can later be dissipated into the circuit as needed. Capacitors connected in series produce less capacitance than capacitors connected in parallel.
