You have an electrical circuit with an ammeter, voltmeter, and a resistor. The ammeter reads 2 A, the voltmeter reads 12 V. Calculate the resistance of the resistor using Ohm's Law. Explain the steps taken.
💡 Hint: Recall that Ohm's Law defines the relationship between voltage, current, and resistance.
A household circuit has a fuse rated at 10A. If the current exceeds this rating and the fuse blows, discuss the consequences and safety measures involving circuit breakers in comparison.
💡 Hint: Consider how reliability and safety are enhanced with modern circuit protection systems.
