### Understanding Electrical Circuits with Resistors and Meters This educational section explains simple resistor and meter circuits, focusing on voltmeters and ammeters placements. The following diagrams illustrate different configurations for measuring voltage and current in a series circuit. #### Circuit Diagrams Explanation - **First Circuit: Voltage Measurement in Series** In this circuit, the voltmeter (V) is placed across the 7 kΩ resistor. The total resistance is composed of three resistors: 2 kΩ, 7 kΩ, and 5 kΩ connected in series. The total voltage supply is +21 V. The voltmeter measures the voltage drop across the 7 kΩ resistor. - **Second Circuit: Voltage Measurement Across Combined Resistors** Here, the voltmeter (V) is placed across the combination of the 7 kΩ and 5 kΩ resistors. All three resistors (2 kΩ, 7 kΩ, and 5 kΩ) are still in series, with a +21 V supply. The voltmeter measures the voltage drop across both the 7 kΩ and 5 kΩ resistors together. - **Third Circuit: Current Measurement in Series** The ammeter (A) is positioned to measure the current flowing through the 7 kΩ resistor. The resistors are again in series, with a total supplied voltage of +21 V. The ammeter measures the current passing through the 7 kΩ resistor specifically. - **Fourth Circuit: Current Measurement Through Entire Series** In this configuration, the ammeter (A) is placed between the 2 kΩ resistor and ground, measuring the current through the entire series combination of all three resistors (2 kΩ, 7 kΩ, and 5 kΩ) under the +21 V supply. #### Key Points - **Series Circuits**: In a series circuit, the current is the same through all components but the voltage drop across each resistor varies based on its resistance. - **Voltmeters**: These are connected in parallel with the component across which the voltage is to be measured. - **Ammeters**: These are connected in series with the circuit component through which the current is to be measured. Understanding these configurations helps in precise measurement of electrical parameters, crucial for analyzing and troubleshooting circuits.
