A

GUGLIELMO MARCONI

18
Q

It’s first use as Amplifier for Electric Signals

A

VACUUM TUBE

19
Q

Ohm’s Law states that:

A

CURRENT IS DIRECTLY PROPORTIONAL TO THE VOLTAGE AND INVERSELY PROPORTIONAL TO THE RESISTANCE

20
Q

KDKA Station uses what type of Modulation

A

AMPLITUDE MODULATION RADIO BAND

21
Q

Solid State Devices that Replace Vacuum Tubes usually made of Silicon And Germanium

A

TRANSISTOR

22
Q

It convert alternating current to direct current or as rectifier , voltage multiplier clipper and clamper

23
Q

Give Three Types Active Electronics Components

A
  1. SEMICONDUCTOR
  2. ELECTRON TUBES
  3. VISUAL DISPLAY DEVICES
24
Q

Give three types of Passive Electronic Components

A
  1. RESISTOR
  2. CAPACITOR or CONDENSER
  3. INDUCTOR or COILS or CHOKES
25
It transmit electromagnetic radio waves
TRANSMITTER
26
It Receives the Transmitted electromagnetic radio waves
RECEIVER
27
It is an important characteristic of any varying Voltage and Current to specify how fast the Amplitudes Change
FREQUENCY
28
it means Radiation for Wireless Transmission . Also Abbreviated form of Radiotelegraph and Radiotelephone
RADIO
29
Capacitance Formula
C= E (A/D) Where E= Permittivity A= Area D= Width of Depletion
30
It is the opposition to the Change of Current
INDUCTANCE
31
Formula of Inductance
L=N^2(uA/l) ``` Where N is number of turns A is Area u is permeability l is Length ```
32
It is the reciprocal of Resistance and the unit is Siemens formerly Mho
Conductance
