Here are the essential concepts you must grasp in order to answer the question correctly.
Ohm's Law
Ohm's Law states that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor. This relationship is expressed mathematically as V = IR. Understanding this law is essential for analyzing circuits, as it allows us to calculate the current through each resistor when the voltage and resistance values are known.

Kirchhoff's Laws
Kirchhoff's Laws consist of two fundamental principles for circuit analysis: Kirchhoff's Current Law (KCL) and Kirchhoff's Voltage Law (KVL). KCL states that the total current entering a junction must equal the total current leaving it, while KVL states that the sum of the electrical potential differences (voltage) around any closed circuit loop must equal zero. These laws are crucial for determining the currents in complex circuits with multiple branches.

Steady State in Circuits
The steady state in electrical circuits refers to the condition where all circuit variables (currents and voltages) remain constant over time after transient effects have dissipated. In this state, the circuit has reached equilibrium, and the currents through the resistors can be calculated using Ohm's Law and Kirchhoff's Laws. Understanding the steady state is important for analyzing circuits that have been powered for a sufficient duration, as it simplifies the calculations needed to find the currents.
