Ammeter Reading and Circuit Analysis

An ammeter is a device used to measure the electric current flowing through a circuit. In the given figure, an ammeter reads 3.0 A.

Circuit Analysis

The circuit consists of a battery, a resistor (R1), and the ammeter. The current flows from the positive terminal of the battery, through the ammeter, the resistor, and back to the negative terminal of the battery.

The equivalent resistance of the circuit is R1, as there are no other resistors connected in parallel.

Ammeter Reading

The ammeter reading of 3.0 A indicates that 3.0 coulombs of charge flow through the circuit every second.

Factors that affect the ammeter reading include the battery voltage, the resistance of the circuit, and the internal resistance of the ammeter.

Circuit Modifications

Modifying the circuit can change the ammeter reading. Here are some possible modifications and their effects:

• Increasing the battery voltage will increase the current flow and the ammeter reading.
• Increasing the resistance of the resistor (R1) will decrease the current flow and the ammeter reading.
• Adding a resistor in parallel with R1 will decrease the equivalent resistance of the circuit, increasing the current flow and the ammeter reading.
