Question 1 of 5
What is the unit of electric current?
Current is measured in Amperes, representing the flow of charge.
Question 2 of 5
Which law states that the voltage across a resistor is directly proportional to the current flowing through it?
Ohm's Law (V = IR) defines the relationship between voltage, current and resistance.
Question 3 of 5
In a series circuit, what is the same across all components?
In a series circuit, the same current flows through each component.
Question 4 of 5
What is the equivalent resistance of two 10-ohm resistors connected in parallel?
Parallel resistance: 1/R_eq = 1/10 + 1/10, therefore R_eq = 5 ohms.
Question 5 of 5
What is the voltage across a 5-ohm resistor if 2 amps of current are flowing through it?
Using Ohm's Law (V=IR), V = 2A * 5? = 10V
