Explanation

• An ammeter is specifically designed to measure electric current.
• A multimeter can also measure current, voltage, and resistance.
• Electric current is measured in amperes (A).
• An ammeter is connected in series with the circuit to measure current.

Additional information:

• Voltmeter: Measures voltage.
• Ohmmeter: Measures resistance.

Explanation

• The correct mathematical form is V = IR.
• Here V = voltage, I = current, R = resistance.
• Ohm’s law states that current is directly proportional to voltage when temperature is constant.
• It describes the relationship between voltage, current, and resistance.
