Understanding Ohm's Law and Circuit Resistance

What does Ohm's Law state about the relationship between voltage and current for a given resistor?

• Current is constant regardless of voltage.

• Voltage is constant regardless of current.

• Voltage and current are directly proportional.

• Voltage and current are inversely proportional.

In a series circuit, how is the total voltage across the circuit determined?

• It is the difference between the highest and lowest voltages.

• It is the sum of the voltages across each resistor.

• It is the product of the voltages across each resistor.

• It is the average of the voltages across each resistor.

How does the current behave in a series circuit?

• It remains the same across all resistors.
