Q1. What will resistances connected to a source of voltage in series do? ...

Ans.

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.

Q2. What are passive and active electrical components? ...

Ans.

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.
