Electrical Circuits and Waves Study Guide

What are the three essential components of a basic electrical circuit?

• Resistor, Voltage, Inductor

• Battery, Conductor, Device

• Switch, Battery, Transformer

• Resistor, Transistor, Battery

Why are homes typically wired with parallel circuits instead of series circuits?

• To save energy

• To allow devices to operate independently

• To reduce wiring costs

• To increase voltage.

What does amplitude measure in a wave?

• Frequency

• Speed

• Height

• Wavelength

Explain the difference between an open and closed circuit.

• Open circuit allows current to flow, closed does not

• Closed circuit allows current to flow, open does not

• Both allow current to flow

• Neither allows current to flow.
