Circuits Flashcard

Front

In a series circuit, if one component is removed or fails, what happens to the other components?

Back

They stop working

Front

In a parallel circuit, how does the voltage across each branch compare?

Back

It is the same across each branch.

Front

What is the primary characteristic of a parallel circuit?

Back

Current can flow through multiple paths.

Front

In a series circuit with 3 identical resistors, how does the total resistance compare to the resistance of each individual resistor?

Back

Total resistance is the sum of all resistance.

Front

How does adding more resistors in series affect the total resistance of the circuit?

Back

Total resistance increases

Front

If one branch of a parallel circuit containing a light bulb is disconnected, what happens to the brightness of the remaining bulbs?

Back

The brightness remains unchanged

Front

Which of the following is an advantage of using parallel circuits in home wiring? Options: If one appliance fails, others are unaffected, The total voltage is divided among all devices, It uses less wiring than a series circuit, It reduces energy consumption

Back

If one appliance fails, others are unaffected

Front

What happens to the total current in a parallel circuit when more branches are added?

Back

The total current increases

Front

In a parallel circuit, how does the total resistance compare to the individual resistances of each branch?

Back

Total resistance is less than the smallest branch resistance.

Front

What is the main reason series circuits are not used in household wiring?

Back

Adding too many devices would cause them all to fail if one stops working.
