Question 1 of 10

What is the unit of measurement for voltage?

Voltage is measured in Volts, which represents the potential difference.
Question 2 of 10

What is the unit of measurement for electric current?

Electric current is measured in Amperes, representing the flow of charge.
Question 3 of 10

What is the unit of measurement for resistance?

Resistance is measured in Ohms, indicating opposition to current flow.
Question 4 of 10

Which of the following equations represents Ohm's Law?

Ohm's Law states Voltage (V) equals Current (I) multiplied by Resistance (R).
Question 5 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 6 of 10

If a circuit has a current of 2A and a resistance of 10?, what is the voltage across the circuit?

Using V = I*R, 2A * 10? = 20V.
Question 7 of 10

If a circuit has a voltage of 6V and a current of 3A, what is the resistance of the circuit?

Using R = V/I, 6V / 3A = 2?.
Question 8 of 10

What happens to the current in a circuit if the voltage is doubled and the resistance remains the same?

According to Ohm's Law, current is directly proportional to voltage.
Question 9 of 10

What happens to the current in a circuit if the resistance is doubled and the voltage remains the same?

Current is inversely proportional to resistance (I = V/R).
Question 10 of 10

Ohm's Law applies primarily to which type of circuit components?

Ohm's Law describes the relationship in resistive components (resistors).
