Ohm's law
Ohm’s law is a prominent concept in physics and electronics. It gives the relation between the current and the voltage. It is used to analyze and construct electrical circuits. Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it.
Path of Least Resistance
In a series of alternate pathways, the direction of least resistance is the actual or metaphorical route that offers the least resistance to forwarding motion by a given individual or body.

**Problem Statement:**
Consider the circuit shown in the figure below. (Assume \( R_1 = 16.0 \, \Omega \) and \( R_2 = 7.50 \, \Omega \).)
**Circuit Diagram Description:**
- The circuit includes a 25.0 V voltage source located at the left side of the diagram.
- The positive terminal of the voltage source is connected to point \( b \) through a wire.
- Connected in series with the voltage source is a resistor \( R_1 \) with a resistance of 16.0 Ω.
- Point \( a \) is located at the connection between resistor \( R_1 \) and a parallel arrangement of two branches.
- The first branch from point \( a \) includes a second resistor \( R_1 \) connected to point \( b \).
- The second branch consists of a resistor \( R_2 \) with a resistance of 7.50 Ω and a third resistor with a resistance of 20.0 Ω in series, connecting points \( a \) and \( c \), then \( c \) to \( b \).
