Q: State Ohm’s Law and derive formulas for series and parallel combination of resistors.
Answer:
Ohm’s Law:
Ohm’s Law states that current through a conductor is directly proportional to the potential difference across its ends provided temperature remains constant.
Formula:
V = IR
In series circuit, resistors are connected end to end.

Packet Filtering Firewall: Filters packets using IP, port, and protocol rules at network layer, providing fast but basic stateless security. Circuit-Level Gateway: Verifies session establishment like TCP handshake at session layer without checking actual data content. Stateful Inspection Firewall: Tracks active connections and uses context-based decisions, offering better security than packet filtering. Application-Level Gateway: Works as a proxy and inspects application data at Layer 7, ensuring
maintainability
maintainability is the ease and speed with which a system or product can be restored to its normal operating condition after a failure occurs.
it is a design quality that focuses on reducing the time and resources required for repairs through features like modularity and accessibility.
mean time to repair (mttr)
mttr is the average time taken to repair a failed component or system and return it to service.
it includes the time spent on discovery, analysis, actual repair work, and
