Introduction to Ohm and Resistance Quiz
easy
5 Questions
Question 1 of 5
What is the unit of measurement for electrical resistance?
Resistance is measured in Ohms, named after Georg Ohm.
Question 2 of 5
Ohm's Law states the relationship between voltage (V), current (I), and resistance (R). Which equation correctly represents this relationship?
Ohm's Law states Voltage equals Current multiplied by Resistance.
Question 3 of 5
If a circuit has a voltage of 12V and a resistance of 4?, what is the current flowing through the circuit?
Using Ohm's Law (I = V/R), I = 12V / 4? = 3A.
Question 4 of 5
Which component in an electrical circuit opposes the flow of current?
A resistor is designed specifically to impede current flow.
Question 5 of 5
What happens to the current in a circuit if the resistance increases, assuming the voltage remains constant?
According to Ohm's Law, if resistance increases and voltage is constant, current decreases.
