Help me with this question, please
How will the total voltage of a string of light bulbs in series change as you add more bulbs to the string?
A. The total voltage will decrease
B. The total voltage will stay the same
C. The total voltage will increase
d. You cannot predict what will happen to the voltage
it stays the same. Why would it change?
okay, thx for the help :)
If it is a series, V_T should be the same.
To understand how the total voltage of a string of light bulbs in series changes as you add more bulbs, let's go through the explanation step-by-step:
In a series circuit, when multiple components (in this case, light bulbs) are connected end-to-end along the same path, the current flowing through each component is the same. However, the total voltage across the entire circuit is divided among the components.
To find the answer, we need to consider the behavior of light bulbs in a series circuit. Light bulbs are resistive components, which means they provide resistance to the flow of electric current. As current flows through a resistor, voltage is dropped across it, according to Ohm's Law (V = I × R), where V represents voltage, I represents current, and R represents resistance.
In a series circuit, the resistances of the individual light bulbs add up. So, as we add more light bulbs to the series circuit, the total resistance of the circuit increases. Since the total voltage across the circuit remains constant (determined by the power source), and voltage is divided among the components based on their resistance, adding more resistive components (light bulbs) will result in a higher total voltage drop across the circuit.
Therefore, the correct answer to the question "How will the total voltage of a string of light bulbs in series change as you add more bulbs to the string?" is:
C. The total voltage will increase.
