We will examine four electric circuits listed in the table below, analyzing their voltage and resistance values to gain a deeper understanding of their characteristics.
Electric Circuit Analysis
Electric circuits are composed of various components, including voltage sources, resistors, and conductors. The behavior of these components is governed by the laws of physics, specifically Ohm's Law, which states that the current flowing through a conductor is directly proportional to the voltage applied and inversely proportional to the resistance of the conductor.
Ohm's Law
Ohm's Law is a fundamental principle in electric circuit analysis, and it is expressed mathematically as:
I = V/R
Where:
- I is the current flowing through the conductor (measured in amperes, A)
- V is the voltage applied to the conductor (measured in volts, V)
- R is the resistance of the conductor (measured in ohms, Ω)
