Several pieces of equipment can be used to verify Ohm's law, including:
1. Voltage source: A power supply or battery can be used to provide a constant voltage across the circuit.
2. Ammeter: An ammeter is used to measure the current flowing through the circuit. It is placed in series with the circuit.
3. Voltmeter: A voltmeter is used to measure the voltage across the circuit. It is connected in parallel with the circuit.
4. Resistor: A known resistor can be used to create a circuit and verify Ohm's law by varying the voltage and measuring the current. The resistance value can be adjusted to observe the relationship between voltage, current, and resistance.
5. Multimeter: A multimeter is a versatile device that combines the functionality of an ammeter, voltmeter, and ohmmeter. It can measure voltage, current, and resistance.
6. Breadboard or circuit board: These are used to assemble the circuit components and establish the connections between them.
7. Connecting wires: Wires are needed to connect the various components of the circuit.
8. Crocodile clips or test leads: These are used to make secure connections between the components and the measuring instruments.
9. Variable resistors: These resistors allow the resistance value to be changed in the circuit, allowing for different measurements to be taken and Ohm's law to be verified under varying conditions.
Using a combination of these equipments, one can set up different circuits, measure the voltage and current, and observe the relationship between them to verify Ohm's law.
