Multiple Choice

Which of the following statements about light is correct?

• Light is part of the electrical spectrum.

• Light can be dispersed into the spectrum of colours, each with different wavelengths.

• Light is made of only two primary colours: red and blue.

• Light is not related to the electromagnetic spectrum.

Multiple Choice

Which instrument is used to measure current in a circuit, and how should it be connected?

• Voltmeter, in parallel

• Ammeter, in series

• Ammeter, in parallel

• Voltmeter, in series

Multiple Choice

Based on the diagrams and data, which circuit type would result in brighter bulbs and why?

• Series circuit, because current is higher

• Parallel circuit, because voltage is higher across each bulb

• Series circuit, because voltage is higher across each bulb

• Parallel circuit, because current is lower

Fill in the Blanks

In a series circuit, the voltage across Bulb 1 is

V.

Multiple Select

Fill in the Blanks

In a series circuit, the total voltage is

between the components.

Multiple Select

In a parallel circuit, what happens to the current when more bulbs are added?

• Current increases
