Bipolar transistors contain three pins namely the emitter, collector, and base.
They store energy as magnetic fields that will generate when there is a flow of current.
The more the number of wire windings, the greater the magnetic field, inductance.
These parts enable the flow of current in a single direction, from the positive anode to the negative cathode.
It performs this by having no resistance in a single direction and high resistance in the opposite direction.
Besides, it prevents damage from occurring on the circuit breaker PCB.
These parts operate as timers, amplifiers, memory, or oscillators.
ICs are small wafers that are made from silicon, able of holding up to millions of transistors, capacitors, and resistors.
This part will transfer the electrical energy from one circuit to the next circuit by increasing or decreasing the voltage.
These parts detect environmental changes and produce electronic signals that correspond to that change.
This signal is then relayed to other electronic parts within the circuit.
They change energy from a physical situation to electrical energy, basically working as transducers.
This is a type of variable resistor available as rotary or linear.
Rotating the knobs of rotary potentiometers will vary the resistance since the slider contact moves over semi-circular resistors.
In linear potentiometers, moving the slider contact linearly on the resistor will vary the resistance.
These parts ensure the electronic device operates correctly and on time by providing the clock in several circuits.
They are vital at interrupting current.
Silicon-Controlled Rectifiers [SCR] or Thyristors
These are semiconductor switches that control high amounts of power through small signal inputs.
