DC Series circuits explained - The basics working principle

The video tutorial explains series circuits, focusing on the flow of electrons, resistance, current, voltage, and power consumption. It covers how components are connected in series, the calculation of total resistance, and the measurement of current and voltage. The tutorial also discusses the concept of voltage drop across resistors and how power is consumed and converted into heat in a series circuit.

What is the main characteristic of a series circuit regarding the path of electron flow?

• Electrons have multiple paths to flow through.

• Electrons flow through a single path.

• Electrons do not flow in a series circuit.

• Electrons flow in a circular path.

How do you calculate the total resistance in a series circuit?

• Subtract the smallest resistance from the largest.

• Divide the largest resistance by the smallest.

• Multiply the resistances of all components.

• Add together the resistances of all components.

What unit is used to measure current in a circuit?

• Watts

In a series circuit, how does the current behave throughout the circuit?

• It only flows through the first component.

• It doubles after each component.

• It varies at different points.

• It is the same throughout the circuit.

What happens to the voltage across each resistor in a series circuit?

• It is only present at the first resistor.

• It is divided among the resistors.

• It remains constant across all resistors.

• It increases with each resistor.

How can you increase the total voltage in a series circuit?

• By adding more resistors.

• By wiring more batteries in series.

• By decreasing the resistance.
