Electrical Current Review

What is the main characteristic of current electricity?

• A steady flow of electrons along a circuit

• A random movement of protons

• A stationary charge

What needs to happen for static electricity to occur?

• A build-up of electrons on a surface

• A constant flow of water

• A reduction in air pressure

What is an example of static electricity?

• A flowing river

• Lightning

• A burning candle

What is static electricity?

• A continuous flow of electrons

• A single, sudden transfer of electrons

• A constant movement of neutrons

How does electricity get to our houses?

• Through wireless transmission

• Through power lines and transformers

• Through solar panels directly

Which of the following is an example of a source of Direct Current (DC)?

• Batteries

• Alternators

• Generators

What is Direct Current (DC)?

• Current in which electric charges move in one direction

• Current in which electric charges move in multiple directions

• Current that does not involve electric charges

What are the two types of currents?

• Direct current and alternating current

• Static current and dynamic current

• High current and low current

What is alternating current?

• Current that flows in a loop

• Current that flows in one direction, then in the reverse direction

• Current that flows randomly

Where is alternating current commonly used?

• In car batteries

• In solar panels

• In homes
