All elements of an electric circuit are connected in series except :a)voltmeterb)ammeterc)rheostatd)resistorCorrect answer is option 'A'. Can you explain this answer?

Question

Answer

Because voltmeter is always connected in parallel nad its measure voltage

Answer

Voltmeter is connected in parallel combination because in parallel combination the potential difference across the circuit is same and therefore it will read correct. If voltmeter is connected in series combination, it will read wrong because potential difference  across appliances in series combination is different.

Answer

Voltmeters are Connected in parallel

Answer

Introduction
In an electric circuit, elements can be connected in two different ways: series and parallel. In a series circuit, the elements are connected in a chain-like sequence, where the current flows through each element one after the other. In a parallel circuit, the elements are connected side by side, allowing the current to divide and flow through multiple paths. This response explains why the correct answer is option 'A' (voltmeter) in the given question.

Explanation
In a series circuit, all elements are connected one after the other, forming a single path for the current to flow through. In this configuration, the same current passes through each element. However, the potential difference (voltage) across each element may vary depending on its resistance.

Elements in a Series Circuit
1. Resistor: A resistor is an electrical component that restricts the flow of current. It is connected in series to control the amount of current flowing in the circuit.
2. Ammeter: An ammeter is a device used to measure the current flowing through a circuit. It is always connected in series to measure the current passing through a specific point in the circuit.
3. Rheostat: A rheostat is a variable resistor that can be adjusted to control the flow of current in a circuit. It is also connected in series to regulate the current.
4. Voltmeter: A voltmeter is used to measure the potential difference (voltage) across different points in a circuit. However, it is not connected in series; instead, it is connected in parallel to measure the voltage across a specific element.

Why Voltmeter is Connected in Parallel?
1. A voltmeter should be connected in parallel to the element whose voltage is being measured. This is because a voltmeter measures the potential difference between two points, and connecting it in parallel ensures it measures the voltage across a specific element only.
2. If a voltmeter is connected in series, it would create a new path for the current and alter the circuit's behavior. It would affect the current flow and the voltage being measured, providing inaccurate readings.
3. By connecting the voltmeter in parallel, it has a very high resistance compared to the circuit's elements. This ensures minimal current flows through the voltmeter, preventing any significant disturbance to the circuit's operation.

Conclusion
In a series circuit, all elements are connected in a chain-like sequence. While elements like resistors, ammeters, and rheostats are connected in series, a voltmeter is connected in parallel to measure the potential difference (voltage) across a specific element. This is done to ensure accurate voltage readings without disturbing the circuit's operation.
