Understanding Ohm's Law Circuit Connections

What is the first step in setting up the Ohm's Law circuit?

• Attach the ammeter to the resistor.

• Turn on the battery.

• Connect the voltmeter in parallel.

• Insert the alligator clip into the battery's positive terminal.

Which terminal of the ammeter should be connected to the key?

• The terminal with the lowest resistance.

• The red positive terminal.

• The terminal with the highest resistance.

• The black negative terminal.

How should the voltmeter be connected in the circuit?

• In series with the battery.

• In series with the resistor.

• In parallel across the load.

• Directly to the ammeter.

What happens to the potential difference across the resistor as the battery voltage increases?

• It fluctuates randomly.

• It increases in proportion.

• It remains constant.

• It decreases.

What is the purpose of varying the rate resistance in the circuit?

• To disconnect the circuit.

• To observe changes in voltage and current.

• To decrease the current flow.

• To increase the battery voltage.
