1. The problem is to understand how to solve questions involving an ammeter, which measures electric current in a circuit. 2. The key formula to remember is Ohm's Law: $$I = \frac{V}{R}$$ where $I$ is the current (measured by the ammeter), $V$ is the voltage, and $R$ is the resistance. 3. Important rules: - The ammeter is connected in series with the circuit element whose current you want to measure. - The ammeter ideally has very low resistance to avoid affecting the circuit. 4. To find the current using an ammeter question, identify the voltage across the component and the resistance, then apply Ohm's Law. 5. Example: If a circuit has a voltage of 12 volts and a resistance of 4 ohms, the current is $$I = \frac{12}{4} = 3$$ amperes. 6. Always check if the question provides total voltage and total resistance or individual components to calculate current. 7. If multiple resistors are involved, calculate the equivalent resistance first before applying Ohm's Law. 8. Remember, the ammeter reading is the current flowing through the circuit at the point where it is connected.
