Answer the following question given this paragraph: The use of electric current to encode information is called electronics. Electronic signals may be digital or analog signals. Both types of signals encode information by changing the voltage of an electric current, but they do so in different ways. Q: What do we call use of electric current to encode information? Choices: - products - metals - ferious - electronics A:
**Answer**
electronics

Answer the following question given this paragraph: There are two ways to control the current in a circuit. Since the current is directly proportional to the potential difference and inversely proportional to the resistance, you can increase the current in a circuit by increasing the potential or by decreasing the resistance. Q: Besides increasing the potential, how else can you increase current in a circuit? Choices: - increasing the resistance - increasing the heat - decreasing the heat - decreasing the resistance A:
**Answer**
decreasing the resistance

Answer the following question given this paragraph: The earth is also a conductor. Touching a charged object to the earth is called grounding . When you touch a conductor to the earth, you allow the earth to share the charge. Since the earth is billions of times bigger than the object, the earth takes nearly all of the charge. The charged object that was grounded now has zero charge. Q: What is it called when you touch a charged object to the earth? Choices: - cooling - charging - dispersion - grounding A:
**Answer**
grounding
