What is the total resistance in a series circuit with resistors of 10 ohms, 15 ohms, and 5 ohms?

Back

Total resistance = 10 + 15 + 5 = 30 ohms.

Front

Define a series circuit.

Back

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

Front

What is the total resistance in a parallel circuit with two resistors of 10 ohms each?

Back

Total resistance (R) = 1 / (1/R1 + 1/R2) = 1 / (1/10 + 1/10) = 5 ohms.

Front

Define a parallel circuit.

Back

A parallel circuit is a type of electrical circuit in which the components are connected across common points or junctions, providing multiple paths for the current.

Front

In a series circuit, how does the current behave?

Back

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

Front

In a parallel circuit, how does the voltage behave across each component?

Back

The voltage across each component in a parallel circuit is the same.

Front

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

Back

The total resistance increases.

Front

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

Back

The total resistance decreases.

Front

If one component in a series circuit fails, what happens to the circuit?

Back

The entire circuit is broken and current stops flowing.

Front

If one component in a parallel circuit fails, what happens to the circuit?

Back

The other components continue to operate; the circuit remains functional.
