What happens if an ammeter is connected in parallel?

Question

Answer

Bcz the resistance of ammeter is zero....

Answer

If you connect the ammeter in parallel then short circuit will happen when there is nearly no resistance in a wire, and when a high current almost infinite flowing through the wire, causing high temperature. Because ammeter has a low resistance and current choose the lowest path to flow.

What happens if an ammeter is connected in parallel?

When an ammeter is connected in parallel, it can have serious consequences and potential damage to the ammeter and the circuit. Let's delve into the details of what happens in such a scenario.

1. Purpose of an ammeter:
An ammeter is a measuring instrument used to measure the electric current flowing through a circuit. It is designed to be connected in series with the circuit, meaning the current flows through the ammeter itself, allowing it to accurately measure the current.

2. Parallel connection:
Connecting an ammeter in parallel means connecting it across a branch or component of the circuit, where the current is expected to flow. In this configuration, the ammeter becomes a part of the parallel branch, and the current will split between the ammeter and the component it is connected across.

3. Implications of parallel connection:
When an ammeter is connected in parallel, the following implications arise:

a. Current division:
Since the ammeter is now in parallel with the component, the total current that flows through the branch will divide between the component and the ammeter. This division of current can lead to inaccurate readings on the ammeter and incorrect measurements of the actual current flowing through the circuit.

b. Additional resistance:
The ammeter itself has a certain resistance, known as its internal resistance. When it is connected in parallel, this internal resistance is effectively added to the parallel branch. This additional resistance alters the overall resistance of the branch, affecting the current flow and potentially causing voltage drops across the ammeter.

c. Damage to the ammeter:
Since an ammeter is designed to measure the current flowing through it, connecting it in parallel can subject it to excessive currents beyond its rated capacity. This can damage the ammeter and render it inaccurate or nonfunctional.

d. Circuit malfunction:
The presence of an ammeter in parallel can disrupt the functioning of the circuit, especially if the circuit relies on the accurate flow of current. The added resistance and altered current division can lead to unexpected behavior or malfunctioning of the circuit components.

Conclusion:
Connecting an ammeter in parallel is fundamentally incorrect and can have severe consequences. It can lead to inaccurate readings, additional resistance, damage to the ammeter, and circuit malfunction. It is crucial to always connect an ammeter in series to ensure accurate current measurements and avoid any potential harm to the circuit or the ammeter itself.
