An electrical appliance has a faulty casing, and without earthing, the user experiences a shock. If the resistance of the fault path through the user is 50 ohms, calculate the safe path required for current flow if the appliance is operating on 240 volts.
💡 Hint: Use Ohm's Law to find the current and think about what resistance is needed.
Consider a lightning strike hitting a building. Describe how the earthing system should function to prevent damage and ensure safety.
💡 Hint: Think about the role of grounding in high voltage scenarios.
