AC(Alternate current)
Alternate current is that thing when positive(+) & negative(-) both flow in a cycle or flow with each other.
& 50cycles = 1 signal
DC(Direct current)
Direct current is that thing when positive(+) & negative(-) flow in different.
COMPONENTS
CAPACITOR
Capacitor is a two pin component.It uses with base of the work in electronic circuit.Capacitor shows by "c".and it's value check by PF, K PF & M F.
KIND OF CAPACITOR
- Simple capacitor
- Non pollerytic
- Electrolytic
Resistance
Resistance make resistivity on the way of current.It shows by "R".Resistance only a component which can make resistivity on way of current.so use for do low value of volt & signals.
KINDS OF RESISTANCE
- Carbon resistance
- Wire wound resistance
- Network resistance
- Chip resistance
- VDR
- LDR
- Thermister
Diode
Diode
is a two leg (head) component.1 leg is ANODE(+/positive) and second is
cathode(-/negative).It's made by P & N type semiconductor.IT is a
one way work component and show by "d".Diode checks by "OMS".
TYPE OF DIODE
- Signal diode
- Photo diode
- Rectifier diode
- LED
- Zen-er diode
- Tunnel diode
- variation diode
Transistor
Transistor is a 3 pin component.1 pin base , 1 pin emitter & 1 pin collect er.It shows by "Q".We get it's value by
oms.There is two type of transistor.
KINDS OF TRANSISTOR
- N-P-N
- P-N-P
