Series circuits - Flashcard

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

In a series circuit, how does the current behave?

Back

The current is the same at all points in a series circuit.

Front

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

Back

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

Front

How is voltage distributed in a series circuit?

Back

The voltage across each resistor adds up to the total voltage of the circuit.

Front

What occurs if one component in a series circuit fails?

Back

If one component fails (like a burned-out bulb), the entire circuit is broken and all components stop working.

Front

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

Back

Total resistance (R_total) = R1 + R2 + R3 + ... + Rn.

Front

What does the circuit symbol for a battery look like?

Back

A battery symbol typically consists of two parallel lines, one longer (positive terminal) and one shorter (negative terminal).

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 is the effect of adding more batteries in series?

Back

Adding more batteries in series increases the total voltage supplied to the circuit.

Front

How does the brightness of bulbs in a series circuit compare?

Back

All bulbs in a series circuit will have the same brightness if they are identical, as they share the same current.
