Basic Electricity: Understand how electricity works Lab

If in our previous exercise 10 Coulombs passed through a certain point in 5 seconds. What is the current in our circuit? a. 1 A b. 2 A c. 5 A d. 10 A

b. 2 A

Why do you think that the light bulb has exploded? a. because the lamp was faulty b. because the battery provided too much energy to the light bulb c. because the battery provided too little energy to the light bulb d. because the battery was fauly

b. because the battery provided too much energy to the light bulb

How many Coulombs passed through the red area in the circuit? a. 20 C b. 3 C c. 10 C d. 5 C

c. 10 C

The light bulb looks very dim. Why do you think this is happening? You can hover over the battery and light bulb to get more information. a. the light bulb is probably broken b. the electrons are not moving c. the voltage provided by the battery is too low d. the current provided by the battery is too low

c. the voltage provided by the battery is too low

We have seen that the volts are used by the different components in the circuit. What would happen to the current expressed in Amperes? a. it decreases every time that it passes through the light bulb b. it increases every time that it passes through the light bulb c. it increases every time that it passes through the battery d. it remains constant, the number of Coulombs flowing in the circuit is always the same

d. it remains constant, the number of Coulombs flowing in the circuit is always the same
