What is one key difference between series and parallel circuits in terms of voltage distribution?

• In series circuits, voltage is divided equally across all components, while in parallel circuits, it is the same across each component.

• In series circuits, voltage increases with each component, while in parallel circuits, it decreases.

• In series circuits, voltage is the same across each component, while in parallel circuits, it varies.

• In series circuits, voltage is zero across all components, while in parallel circuits, it is maximum.

Why are circuit breakers and fuses important in electrical circuits?

• They enhance the flow of electricity.

• They prevent excessive electrical charge.

• They prevent damage from overcurrent by breaking the circuit.

• They increase the voltage to safe levels.

Which formula is used to calculate electric power in a circuit?

• Power = Voltage x Current

• Power = Current / Voltage
