Question 1 of 10
What is the SI unit of electric current?
The SI unit of electric current is the Ampere (A), named after André-Marie Ampère.
Question 2 of 10
Which of the following formulas represents Ohm's Law?
Ohm's Law states that Voltage (V) is equal to Current (I) multiplied by Resistance (R).
Question 3 of 10
What is the primary cause of current flow in a circuit?
Voltage creates the potential difference that drives the flow of current.
Question 4 of 10
How is current typically represented in electrical formulas?
Current is represented by the symbol 'I' in electrical formulas.
Question 5 of 10
What is the unit of measurement for voltage?
The unit of measurement for voltage is the Volt (V).
Question 6 of 10
What is the formula for calculating current in a DC circuit, based on Ohm's Law?
According to Ohm's Law, current (I) is equal to voltage (V) divided by resistance (R).
Question 7 of 10
What does 'AC' stand for in the context of electrical current?
AC stands for Alternating Current, which periodically reverses direction.
Question 8 of 10
What is the formula to calculate Voltage in a DC circuit?
All of the given formulas are valid ways to calculate voltage in a DC circuit, depending on what values are known.
Question 9 of 10
Which type of current changes its magnitude and direction over time?
Alternating Current (AC) is characterized by its continuously changing magnitude and direction.
Question 10 of 10
In a 3-phase AC circuit (Star connection), what is the relationship between Line Voltage (VL) and Phase Voltage (VPH)?
In a Star connection, the Line Voltage is equal to the square root of 3 times the Phase Voltage.
