Ohm's Law and Circuit Analysis Quiz (11)

What is Ohm's Law?

• The relationship between current and resistance only

• The relationship between voltage and current only

• Power equals current squared times resistance

In a series circuit, how does the total resistance compare to individual resistors?

• Total resistance is less than any individual resistor

• Total resistance equals the sum of all resistors

• Total resistance is the average of all resistors

• Total resistance equals the smallest resistor

In a parallel circuit, what remains constant across all branches?

• Current

• Resistance

• Power

• Voltage

How does current flow in a parallel circuit?

• The same current flows through each branch

• Current divides among different paths

• Current flows only through the path of least resistance

• Current increases in each successive branch

What happens to the total current in a series circuit if you add more resistors?

• Increases

• Stays the same

• Decreases

• Multiplies

If voltage remains constant, what happens to current when resistance increases?

• Increases

• Stays the same

• Decreases

• Becomes zero

What is the voltage across each resistor in a parallel circuit?

• Different for each resistor

• Equal to the source voltage

• Half of the source voltage

• One-third of the source voltage
