Question 1 of 10
Which of the following is considered the primary cause of electrocution?
Current is directly responsible for causing harm to the human body, not voltage itself.
Question 2 of 10
According to Ohm's Law, what is the relationship between current and voltage?
Ohm's Law (V = IR) shows that with constant resistance, current increases as voltage increases.
Question 3 of 10
In a circuit with a constant power load, what is the relationship between voltage and current?
If power (P = VI) is constant, increasing voltage decreases current, and vice versa.
Question 4 of 10
If a 100W light bulb is connected to a 120V supply, what is the approximate current flowing through it?
Using P = VI, I = P/V = 100W / 120V ? 0.833 A
Question 5 of 10
If the same 100W light bulb is connected to a 230V supply, what is the approximate current flowing through it?
Using P = VI, I = P/V = 100W / 230V ? 0.435 A
Question 6 of 10
Which voltage level, 120V or 230V, typically results in a higher current for the same wattage load?
For the same power (wattage), a lower voltage requires a higher current (P=VI).
Question 7 of 10
What will happen to a 120V-rated light bulb if it is connected to a 230V supply?
The higher voltage will likely cause the bulb to overheat and burn out.
Question 8 of 10
What is the consequence if a 230V-rated light bulb is connected to a 120V supply?
The lower voltage will cause the bulb to produce less light output (and potentially consume less power than its rated value).
Question 9 of 10
In the context of electrical safety, why is current more dangerous than voltage?
Current is the actual flow of charge that damages biological tissues.
Question 10 of 10
When considering the risk of electrocution, what factor of the human body is most relevant?
The resistance of the body determines how much current flows for a given voltage.
