Why is the current constant in a series circuit?

In summary, in a series circuit, the current remains the same throughout the circuit regardless of the number of resistors. However, the voltage across each resistor may vary. This is because the resistors act as one unit, and the current must flow through each one, but the resistance provided by each resistor will affect the voltage.

I know that in a series circuit the current is the same amperage though out the circuit. What does not make sense to me though, is why it should be that way. For example, if one had a series circuit with just resistors in it, it seems that the resistors would each change the flow of the current by way of providing resistance. I hope that that made sense.

Think of the series resistors as one resistor. So whatever current will flow in, it must flow out. But what will be different is the voltage across every resistor.

Thanks waht.
 

1. What is a series circuit?

A series circuit is a type of electrical circuit in which the components are arranged in a single loop, with the same current flowing through each component.

2. What is the current in a series circuit?

In a series circuit, the current is the same at all points in the circuit. This means that the current flowing through each component is equal.

3. How is the total resistance in a series circuit calculated?

The total resistance in a series circuit is the sum of the individual resistances of each component. This can be calculated using the formula R = R1 + R2 + ... + Rn, where R is the total resistance and R1, R2, etc. are the individual resistances.

4. What happens to the current when more resistors are added in a series circuit?

When more resistors are added in a series circuit, the total resistance increases, which in turn decreases the overall current in the circuit. This is because the current must travel through each resistor, and the more resistors there are, the more resistance the current must overcome.

5. How does the voltage in a series circuit compare to the voltage across individual components?

In a series circuit, the total voltage is divided among the different components. This means that the voltage across each individual component is a fraction of the total voltage, and the sum of the voltage drops across each component is equal to the total voltage.
