ohm's law Quiz
easy
5 Questions
Question 1 of 5
What is the formula for Ohm's Law?
Ohm's Law states that Voltage (V) is equal to Current (I) multiplied by Resistance (R).
Question 2 of 5
If a circuit has a voltage of 12V and a resistance of 4 ohms, what is the current flowing through the circuit?
Using Ohm's Law (I = V/R), I = 12V / 4 ohms = 3A.
Question 3 of 5
What unit is used to measure resistance?
Resistance is measured in Ohms, represented by the symbol ?.
Question 4 of 5
What happens to the current in a circuit if the voltage is doubled and the resistance remains constant?
According to Ohm's Law, if V doubles and R is constant, I must also double (I=V/R).
Question 5 of 5
Which of the following describes the relationship between voltage and current in a circuit with a fixed resistance?
Ohm's Law shows a direct proportionality: V is directly proportional to I when R is constant.
