What are the 2 electronic component?

• Capacitor and Transistor

• Resistor and I.C's

• Amplifier and speaker

• Active and Passive

is a passive component made to provide a definite amount of resistance. In circuits, it limits current flow or provides voltage drop.one point to another

• Resistor

• Transistor

• Power switch

• LED

II.  Decode and Compute the value of the Resistors (20pts).

Answer explanation

1. 1. Brown 1 , Black 0, Red 100ohms , Gold +-5% (J)

2. 10 x100ohms = 1,000ohms +-5%

4. 2. Red 2, Red 2, Brown 10ohms, Yellow no tolerance

5. 22 x 10ohms = 220ohms no tolerance

7. 3. Red 2, Violet 7, Brown 10ohms, Gold +-5% (J)

8. 27 x 10ohms = 270ohms +-5%

10. 4. Orange 3, White 9, Yellow 10Kohms, Silver +-10% (K)

11. 39 x10kohms = 390Kohms +-10%

What is the difference between Active and Passive Device. (10points)

Answer explanation

Active device is any type of circuit component with the ability to electrically control electric charge flow (electricity controlling electricity). Active devices include, but are not limited to, vacuum tubes, transistors, I.C.’s, Silicon-controlled rectifiers (SCRs), and TRIACs and I.C.s

while Passive devices – is an electronic component which can only receive energy, which it can either dissipate, absorb or store it in an electric field or a magnetic field.
