Understanding Voltage in Series Resistors

What is the total voltage provided by the battery in the circuit discussed?

• 21 volts

• 15 volts

• 12 volts

• 9 volts

How does the current behave as it passes through resistors in series?

• It fluctuates

• It decreases

• It increases

• It remains the same

What happens to the energy of the current as it passes through each resistor?

• It doubles

• It remains constant

• It increases

• It decreases

What is the relationship between the voltage drops across resistors and the battery voltage?

• Voltage drops are unrelated

• Voltage drops are greater

• Voltage drops are less

• Voltage drops equal battery voltage

Which law is used to calculate the voltage drop across each resistor?

• Kirchhoff's Law

• Ohm's Law

• Newton's Law

• Coulomb's Law

What is the formula for Ohm's Law?

• V = I + R

• V = I / R

• V = I * R

• V = R / I

What is the current through each resistor in the circuit?
