Series Circuits Flashcardizz

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit in which components are connected end-to-end, so that the current flows through each component in turn.

Front

What happens to the total resistance when resistors are added in series?

Back

The total resistance increases as more resistors are added in series.

Front

What is the formula for total resistance in a series circuit?

Back

R_total = R1 + R2 + R3 + ... + Rn, where R1, R2, R3, etc. are the resistances of individual resistors.

Front

How does current behave in a series circuit?

Back

The current is the same through all components in a series circuit.

Front

What is the effect of adding more resistors in series on the total current?

Back

Adding more resistors in series decreases the total current in the circuit.

Front

What is voltage drop in a series circuit?

Back

Voltage drop is the reduction in voltage across a component in a circuit, which occurs due to resistance.

Front

How do you calculate voltage drop across a resistor in a series circuit?

Back

Voltage drop (V) across a resistor can be calculated using Ohm's Law: V = I * R, where I is the current and R is the resistance.

Front

What is the relationship between voltage, current, and resistance in a series circuit?

Back

According to Ohm's Law, V = I * R, where V is voltage, I is current, and R is resistance.

Front

What happens if one component fails in a series circuit?

Back

If one component fails (like a light bulb), the entire circuit is interrupted and all components stop working.

Front

What is the total current in a circuit with a total resistance of 450 ohms and a voltage supply of 9 volts?

Back

Using Ohm's Law, I = V/R, the total current is 0.02 amps (I = 9V / 450Ω).
