ohms law Quiz
easy
5 Questions
Question 1 of 5
What is the formula for Ohm's Law?
Ohm's Law states that Voltage (V) equals 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 I = V/R, Current = 12V / 4 ohms = 3 Amps.
Question 3 of 5
What unit is used to measure resistance?
Resistance is measured in Ohms, denoted by the symbol ?.
Question 4 of 5
What happens to the current in a circuit if the voltage is doubled and the resistance remains the same?
According to Ohm's Law (I = V/R), if V doubles, and R is constant, I will double.
Question 5 of 5
Which of the following describes the relationship between voltage and current in a circuit, assuming constant resistance?
According to Ohm's Law, voltage and current are directly proportional when resistance is constant.
