Tata Communications Interview Questions, Process, and Tips for Experienced

Q1. What is voltage
Ans. 
Voltage is the electric potential difference between two points, driving current flow in a circuit.
• Voltage is measured in volts (V).

• It represents the energy per unit charge available to move electrons.

• Example: A standard household outlet in the US provides 120V.

• Higher voltage can lead to greater current flow, given a constant resistance (Ohm's Law).

• Voltage can be AC (alternating current) or DC (direct current).
