An electrical circuit is a closed loop through which an electric current can flow. It consists of various components such as resistors, capacitors, inductors, and power sources connected by conductive wires. The components in a circuit work together to control the flow of electricity and perform specific functions.
There are two main types of electrical circuits: series circuits and parallel circuits. In a series circuit, the components are connected in a single path, so the current flows through each component in sequence. In a parallel circuit, the components are connected in multiple paths, so the current can flow through different branches simultaneously.
Understanding electrical circuits is essential for designing and troubleshooting electronic devices, as well as for ensuring the safe and efficient operation of electrical systems. Students studying electrical engineering or related fields often learn about circuit theory, analysis techniques, and circuit design principles to work with circuits effectively.

Assignment: Electrical Circuit Analysis
Objective:
- To analyze and solve basic electrical circuits using Ohm's law, Kirchhoff's laws, and nodal/mesh analysis.
Materials:

- Resistors (various values)
- Power supply (variable voltage, 0-12V)
- Wires
- Breadboard
Procedures:
Part 1: Ohm's Law
1. Build a simple circuit consisting of a power supply, resistor, and digital multimeter in series.
2. Set the power supply to a known voltage.
3. Measure the current through the resistor using the multimeter.
4. Calculate the resistance of the resistor using Ohm's law (R = V/I).
5. Repeat steps 2-4 for different resistors and power supply voltages.
Part 2: Kirchhoff's Current Law
1. Build a circuit with multiple resistors connected in parallel.
2. Set the power supply to a known voltage.
3. Measure the current through each resistor using the multimeter.

Part 3: Kirchhoff's Voltage Law
1. Build a circuit with multiple resistors connected in series.
2. Set the power supply to a known voltage.
3. Measure the voltage across each resistor using the multimeter.

Part 4: Nodal Analysis
1. Build a circuit with multiple resistors and voltage sources.
2. Label nodes in the circuit where currents can enter or leave.
3. Write nodal equations for each node based on Kirchhoff's current law.
