10 Questions
Question 1 of 10
What is the unit of measurement for electric current?
Current is measured in Amperes, representing the flow of charge.
Question 2 of 10
Which of the following is the correct formula for Ohm's Law?
Ohm's Law states Voltage (V) equals Current (I) multiplied by Resistance (R).
Question 3 of 10
If a circuit has a voltage of 12V and a resistance of 4?, what is the current flowing through it?
Using I = V/R, 12V / 4? = 3A.
Question 4 of 10
What is the unit of measurement for electrical resistance?
Resistance is measured in Ohms, representing opposition to current flow.
Question 5 of 10
If a circuit has a current of 2A and a resistance of 10?, what is the voltage across it?
Using V = I*R, 2A * 10? = 20V.
Question 6 of 10
What is the unit of measurement for electrical voltage?
Voltage is measured in Volts, representing the electrical potential difference.
Question 7 of 10
In a series circuit, what is the relationship between the current flowing through each component?
In a series circuit, the current has only one path to flow, so it's the same throughout.
Question 8 of 10
If the voltage in a circuit increases, and the resistance remains constant, what happens to the current?
According to Ohm's Law (I=V/R), current is directly proportional to voltage.
Question 9 of 10
If a circuit has a voltage of 6V and a current of 2A, what is the resistance?
Using R=V/I, 6V / 2A = 3?.
Question 10 of 10
What is the relationship between power, voltage, and current?
Power (P) is calculated as Voltage (V) multiplied by Current (I).
