Patrianna Interview Questions and Answers

Resistors connected in parallel have the same voltage across them, while resistors connected in series have the same current flowing through them.

• In a parallel circuit, the voltage across each resistor is the same.

• In a series circuit, the current through each resistor is the same.

• Parallel resistors have an equivalent resistance calculated as 1/R_total = 1/R1 + 1/R2 + ...

• Series resistors have an equivalent resistance calculated as R_total = R1 + R2 + ...

A capacitor stores electrical energy in an electric field, while a resistor limits the flow of current in a circuit.

• Capacitor stores energy in an electric field

• Resistor limits the flow of current in a circuit

• Capacitors are used in filtering, timing circuits, and energy storage

• Resistors are used to control current flow, voltage division, and heat generation

The symbol for an NPN transistor consists of an arrow pointing outwards from the base.

• NPN transistors have three layers: N-type semiconductor between two P-type semiconductors

• The arrow points away from the base terminal

• Commonly used in amplification and switching circuits
