Q1. Difference between MCB and MCCB
Ans. 
MCB is a miniature circuit breaker used for low voltage applications, while MCCB is a molded case circuit breaker used for higher currents and voltages.
• MCB is designed for low voltage applications, typically up to 1000V, while MCCB is designed for higher currents and voltages, typically up to 2500V.

• MCB is usually thermal-magnetic in operation, while MCCB can be thermal-magnetic or electronic trip units.

• MCB is compact i...read more

Q2. Different types of Breaker
Ans. 
Different types of breakers include circuit breakers, fuse breakers, and ground fault circuit interrupters.
• Circuit breakers: Automatically switch off electrical circuits during abnormal conditions.

• Fuse breakers: Use a fuse to interrupt the circuit when overloaded.

• Ground fault circuit interrupters (GFCI): Detect imbalances in current flow to prevent electrical shocks.

• Miniature circuit breakers (MCB): Provide protection ...read more

Q3. What is Ohm's law?
Ans. 
Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.
• Ohm's law is represented by the equation I = V/R, where I is the current, V is the voltage, and R is the resistance.

• It is named after Georg Simon Ohm, a German physicist who first formulated this law.

• This law is applicable to all types of circuits, including DC and AC circuits.

• It is use...read more
