Electricity & Magnetism Quiz

Match the following

• closed circuit

• devices are linked together with separate pathways or loops; current is split and can take different routes

• open circuit

• continuous circuit without breaks; the switch is closed

• parallel circuit

• circuit with a break; the switch is open

• series circuit

• devices are linked together in a row (one after another) and the current flows sequentially

Match the following

,

(b) conductor

• glass

• wood

• wate

The resistance through a wire depends upon the type of metal, the length of the wire, and the diameter of the wire. Electricity will always choose -

• resistance does not matter to electric current

• it depends on the situation

• the path with the most resistance

• the path with the least resistance

SERIES circuit: What happens to the brightness of the first light bulb as we ADD MORE light bulbs?

• the current (light bulb brightness) INCREASES with each additional bulb

• the current (light bulb brightness) DECREASES with each additional bulb

• the current (light bulb brightness) is NOT affected with each additional bulb

• the current (light bulb brightness) INCREASES or DECREASES depending on the situation

PARALLEL circuit: What happens to the brightness of the first light bulb as we ADD MORE light bulbs?

• the current (light bulb brightness) INCREASES with each additional bulb

• the current (light bulb brightness) DECREASES with each additional bulb

• the current (light bulb brightness) is NOT affected with each additional bulb

• the current (light bulb brightness) INCREASES or DECREASES depending on the situation

Match the following
