Flashcards in Asvab Electronics Deck (24)
Ohms law states ?
Voltage (E) = current (I) x resistance (R)
What do resistors color bands stand for?
1 band mean one digit
2nd band means a second digit
3 band means subsequent zeros
Heaters, pumps, stairs, diving boards, railings, rebar, must be bonded together by
A minimum of #8 wire for safety purposes
Voltage is short for
Electrical potential difference and its measured in volts.
Sims stands for
Subscriber Identity Module
Resistor ____ the flow of current
Resist or inhibits
_____ has two terminals. The anode and the cathode. It restricts current flow to one direction.
____ can operate as high as 100,000 MHz (megahertz)
Electrons in _____ circuit regularly reverse their direction
Alternating currents (AC)
_____ circuit, electrons always flow in the same direction.
Direct current (DC)
The flow of charged particles
Changing Alternating currents (AC) to Direct Currents (DC) is a process called
British thermal unit (BTU) is a
Measure of heat
The presence of electron flow
Transform energy, can be switches, strain gauges, temperature sensors, or inductive switches
Electronic devices that can create energy (voltage supplies + current supplies)
Electronic devices that cannot create energy
Fuses are designed
To prevent current overload at a specific level.
Neutral wire is always
Whitish or neutral colored
Current x Voltage
Electrical power is measured in Watts so you use a _____
An ______ measures amps (current)
An _____ measures ohms (resistance)
