Understanding Series Circuits

Front

What is the main characteristic of a series circuit?

Back

Components are connected end-to-end in a single path

Front

In a series circuit, if one component fails, what happens to the entire circuit?

Back

The entire circuit stops functioning

Front

Which of the following is true about the current in a series circuit? The current varies at different points, The current is the same through all components, The current is zero at the beginning and end, The current flows in multiple loops

Back

The current is the same through all components

Front

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

Back

The total resistance increases.

Front

In a series circuit, how is the total voltage across all components calculated?

Back

By adding the voltages of all components together

Front

What is the formula for calculating total resistance in a series circuit? Options: ( R_t = {1}/{R_1} + {1}/{R_2} + {1}/{R_3} ), ( R_t = R_1 X R_2 X R_3 ), ( R_t = R_1 + R_2 + R_3 ), ( R_t = {R_1 X R_2}{R_1 + R_2} )

Back

( R_t = R_1 + R_2 + R_3 )

Front

Which of the following is a disadvantage of a series circuit? Simple to design and build, Voltage is divided evenly across components, Failure of one component affects the entire circuit, Current remains constant

Back

Failure of one component affects the entire circuit

Front

In a series circuit, the sum of the voltage drops across each component is equal to what?

Back

The supply voltage

Front

What happens to the brightness of bulbs in a series circuit as more bulbs are added?

Back

The brightness decreases

Front

Which of the following is an example of a series circuit in a household?
Options:
Parallel wiring in outlets,
A single string of Christmas lights,
A multi-speed ceiling fan,
A circuit breaker panel

Back

A single string of Christmas lights
