A diode to an electronic circuit is like a _______________ to a city?
parking lot |
|
traffic light |
|
highway |
|
one-way street |
A diode allows current to pass easily in one direction and blocks current in the other direction.
| 60V 20A | |
| 30V 40A | |
| 15V 80A | |
| 60V 80A |
Connecting the 4 batteries in series multiplies their voltage while keeping their current the same yielding a 60V 20A configuration. Connecting the 4 batteries in parallel multiplies their current while keeping their voltage the same yielding a 15V 80A configuration. Using a series-parallel connection, 2 batteries can be connected in series and 2 can be connected in parallel resulting in a 30V 40A configuration.
The rate of flow of electrons per unit time is which of the following?
resistance |
|
voltage |
|
conductance |
|
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 sum of the voltage drops across each resistor in a __________ circuit will equal the total voltage applied to the circuit.
closed |
|
series-parallel |
|
parallel |
|
series |
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.
This circuit component symbol represents a(n):
DC source |
|
AC source |
|
transformer |
|
capacitor |
Direct current flows in only one direction in a circuit, from the negative terminal of the voltage source to the positive. A common source of direct current (DC) is a battery.
