Solving Electric Circuit Problems. When tackling a circuit problem you may need to figure out the equivalent resistance of the circuit, voltage drops across resistors, total current coming out of the battery or current through specific resistors, power dissipated by resistors or provided by the battery, relative brightness of light bulbs in a ...
The document provides example problems and solutions related to electric current and circuits. It addresses topics like calculating current, charge, resistance, power, and internal resistance. One example problem involves calculating the current through different resistors in a series-parallel circuit.
An open circuit means a break in some part of a circuit which could be deliberate such as a key in open position or a fault such as broken wire or burnt out component(s) or loose connection.
Which one of the electric circuits as shown below has the bigger current. Solution : The resistance of the resistor is R and the electric voltage is V. R1, R2 and R3 are connected in series. The equivalent resistor : RA = R1 + R2 + R3 = R + R + R = 3R. Electric current (I) : R1, R2 and R3 are connected in parallel. The equivalent resistor :
This collection of problem sets and problems target student ability to use circuit concept and equations to analyze simple circuits, series circuits, parallel circuits, and combination circuits.
the circuit using the matrix node-voltage method. The plot is: (g) I chose to use 6 different cases, and plotted them below. The code is attached (file named s_hw5_r2rdac_v3_g.m). The code shows my choice of 6 resistors each time.
Complex circuits that cannot be broken down into series and parallel components can be analyzed using Kirchhoff's junction and circuit rules.
