Q

The difference between and transistor and an scr is what

A

Q

What do photo cells/ light dependent resistor (LDR) in a transistor circuit do

A

Detects the absence or presence of light and allows current to flow through the base leg, turning on the transistor

Q

What does a PIR (passive infrared) switch detect

A

Temperature changes and movement in zones

17
Q

What are capacitors used for

A

Power source

Timing delay

18
Q

How are AIR (active infrared) device activated

A

By interrupting the infrared beam

19
Q

How does an RC (resistor/capacitor) circuit work

A

It slows down the flow of electrons pulling them into the capacitor before it allows the base leg to latch activating the transistor

20
Q

What is a transistor

A

An electric switch

21
Q

What function does the base leg of a transistor do

A

Is the trigger and turns on the transistor

22
Q

What causes a collapsing circuit to function

A

Battery decay, cutting the wrong wire, anti-disturbance

23
Q

What causes movement of the contacts in a relay

A

Energizing/de-energizing of the coil

24
Q

What are some products in which you’d find an IC chip

A

Analog: amplifiers, timers, oscillators, voltage regulators

Digital:Microprocessors, memories, microcomputers

25
Q

What are the indicators of a remote controlled device

A

Antennas, servos, battery packs, braided wires
