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.
Question
What is the total power delivered in this circuit? R=9 Ω, V = 6 V
![The diagram is a representation of an electrical circuit consisting of resistors and a voltage source. Here's a detailed explanation:
**Circuit Components:**
1. **Voltage Source (V):**
- Positioned at the bottom of the diagram.
- Denoted by a pair of parallel lines, indicating the positive (+) and negative (-) terminals.
2. **Resistors (R):**
- The circuit contains a total of five resistors, denoted by a zigzag line and labeled "R."
- These resistors are organized into both series and parallel configurations.
**Configuration:**
- **Series Section:**
- One resistor (R) is in series with the other components of the circuit.
- This resistor is on the left side of the circuit, directly connected to the voltage source.
- **Parallel Section:**
- The remaining four resistors are arranged in a parallel configuration.
- Two branches are formed, each containing two resistors in series.
- These two branches are parallel to each other and connect back to the circuit.
**Overall Circuit Description:**
- The entire setup can be considered a series-parallel circuit. The single resistor on the left is in series with a parallel arrangement comprising two branches of series resistors.
- The voltage source is applied across this arrangement, providing the potential difference necessary for the current to flow through the circuit.
Understanding this circuit involves analyzing the effective resistance. The series combination of resistors adds linearly, while the parallel resistors require the application of the formula for parallel resistance:
\[ \frac{1}{R_{\text{parallel}}} = \frac{1}{R_1} + \frac{1}{R_2} \]
This circuit demonstrates fundamental concepts such as Ohm’s Law, series and parallel resistor calculations, and the impact of configuration on total resistance and current distribution.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F7a6c5d3b-e5b8-4c83-98f3-0eb4165b9968%2F15656502-dc5a-4b35-ae44-f2b5a5e1961f%2Fypkwuia_processed.png&w=3840&q=75)
