Efftronics Systems Technical Support Engineer Interview Questions and Answers

Resistances connected in series to a voltage source will reduce the current flowing through the circuit.

• Resistances in series add up to increase the total resistance of the circuit.

• This results in a decrease in current flowing through the circuit.

• The voltage drop across each resistance will be proportional to its resistance value.

• This principle is used in voltage dividers and current limiting circuits.

Passive components do not require an external power source, while active components do.

• Passive components include resistors, capacitors, and inductors.

• Active components include transistors, diodes, and integrated circuits.

• Passive components can only attenuate signals, while active components can amplify and switch signals.

• Passive components are simpler and cheaper than active components.
