Unit 8 - Vocab B

is a unit of measure of the rate of electron flow or current in an electrical conductor. One ampere of current represents one coulomb of electrical charge moving past a specific point in one second.

• capacitor
• amp/ampere
• hard cutoff
• bootloader

is the amount of energy charge in a battery that will allow one ampere of current to flow for one hour.

• channel
• amp hour (Ah)
• back electromotive force (back-EMF)
• OneShot

refers to the number of electrical phase windings on a motor.

• circuit
• 3-phase
• binary code
• soft cutoff

defined as the maximum your motor can cope with for a few seconds (something like 10-15 seconds), in intermittent brief bursts, followed by a cool down periods of lower amp draw.

• current
• burst current
• complementary PWM
• OPTO (Optoisolator)

refers to the process of determining, checking, or rectifying the graduation of something carefully so as to have a precise use and application.

• electron
• calibration
• Constant Discharge Rate
• UBEC (Universal Battery Eliminator Circuit)

describes the proportion of “on” time to the “regular interval” of time.

• ESCs (Electronic Speed Controllers)
• duty cycle
• Encoding
• BEC (Battery Eliminator Circuit)

in engineering is a design feature or practice that in the event of a specific type of failure, inherently responds in a way that will cause no or minimal harm to other equipment, the environment or to people.

• LED (light- emitting-diode)
• failsafe
• exponential function
• BLHeli

a unit that measures electric power over time, commonly used to measure the energy capacity of a battery.

• LiPo (lithium polymer
• mAh (milliampere hours)
• FETs (field effect transistors)
• conductive

a thousandth of a second.

• ohm
• ms (milliseconds)
• firmware
• flashed

a component of a system that divides an electrical power feed into subsidiary circuits.

• Ohm’s Law
• PDB (power distribution board)
• flywheel
• generator
