Electrical Circuit Examples Of Loads And Voltages Pdf

## Introduction An electrical circuit is a path that allows electricity to flow. It consists of a source of electrical energy, such as a battery or generator, and a load, which is something that uses the electrical energy. The load can be a light bulb, a motor, or any other device that requires electricity to operate. The voltage in an electrical circuit is the difference in electrical potential between two points. It is measured in volts (V). The current in an electrical circuit is the flow of electrical charge. It is measured in amps (A). The resistance of an electrical circuit is the opposition to the flow of electrical current. It is measured in ohms (Ω). The following are examples of electrical circuits with different loads and voltages: ## Example 1: A simple circuit with a light bulb This is a simple circuit with a battery, a light bulb, and a switch. When the switch is closed, the battery provides electrical energy to the light bulb, which causes it to light up. The voltage of the battery is 12 volts, and the current flowing through the circuit is 0.5 amps. ## Example 2: A circuit with a resistor This is a circuit with a battery, a resistor, and a light bulb. The resistor is used to limit the current flowing through the circuit. When the switch is closed, the battery provides electrical energy to the resistor, which causes it to heat up. The voltage of the battery is 12 volts, and the current flowing through the circuit is 0.2 amps. ## Example 3: A circuit with a capacitor This is a circuit with a battery, a capacitor, and a light bulb. The capacitor is used to store electrical energy. When the switch is closed, the battery provides electrical energy to the capacitor, which charges up. The voltage of the battery is 12 volts, and the current flowing through the circuit is 0 amps. ## Example 4: A circuit with an inductor This is a circuit with a battery, an inductor, and a light bulb. The inductor is used to store magnetic energy. When the switch is closed, the battery provides electrical energy to the inductor, which causes it to generate a magnetic field. The voltage of the battery is 12 volts, and the current flowing through the circuit is 0 amps. ## Example 5: A circuit with a transformer This is a circuit with a battery, a transformer, and a light bulb. The transformer is used to increase or decrease the voltage in the circuit. When the switch is closed, the battery provides electrical energy to the transformer, which increases the voltage and sends it to the light bulb. The voltage of the battery is 12 volts, and the voltage of the light bulb is 24 volts. ## Conclusion These are just a few examples of electrical circuits with different loads and voltages. There are many other types of circuits, and the combinations of loads and voltages are endless. By understanding the basic principles of electricity, you can design and build circuits to meet your specific needs. ## Resources * [ElectricElectrical Circuits Lecture Notes B Tech I Year Ii Sem 2017 18 Malla Reddy College Of Engineering Technology
