What reading do we get if we measure the voltage across either of the 10 ohm resistors individually?
4.5 volts
What are resistors doing to the voltage in a circuit?
Decreasing it
What happens to the voltage across the resistors in a series circuit?
The voltage decreases across each resistor in the circuit
What effect does adding more resistors have on the total voltage in a series circuit?
It decreases the total voltage across the circuit
What happens to the voltage drop when a 10-ohm resistor is replaced with a 5-ohm resistor in a series circuit?
The voltage drop decreases
What is the purpose of a resistor in an electrical circuit?
To reduce the voltage or pressure in the circuit
How does the resistance of a component affect the voltage drop in a series circuit?
Higher resistance leads to higher voltage drop
What happens to the energy as electrons flow through a resistor in a circuit?
The energy is converted into heat
How is total current affected by adding resistors in a series circuit?
