Expt -1 Study of Active & Passive Components

Tunnel diode can be used as an active device because

• its negative resistance region is used

• it conducts at a faster rate

• it triggers the flow of electrons in reverse bias

• of tunneling effect

For 180K Ω resistor with 10% tolerance, the color band will be in the sequence of

• Brown-Grey-Yellow-Gold

• Brown-Grey-Yellow-Silver

• Brown-Blue-Yellow-Silver

• Brown-Blue-Yellow-Gold

In case of Electrolytic capacitor, if positive terminal is connected with negative of supply and negative terminal is connected with positive of supply

• There will not be any effect

• The capacitor will be damaged

• The circuit will not work

• None of the above
