Question 1 of 10
What does the unit Ohm (Ω) measure?
Ohm (Ω) is the unit for measuring electrical resistance.
Question 2 of 10
Which scientist is Ohm's Law named after?
Ohm's Law is named after Georg Simon Ohm.
Question 3 of 10
What is the basic formula for Ohm's Law?
The basic formula for Ohm's Law is Voltage (V) = Current (I) * Resistance (R).
Question 4 of 10
What happens to current flow in a circuit when resistance increases?
As resistance increases, the current flow decreases.
Question 5 of 10
Which of the following is NOT a factor that influences resistance?
The color of the wire does not affect resistance.
Question 6 of 10
What tool is used to measure resistance?
An ohmmeter is specifically designed to measure resistance.
Question 7 of 10
If a circuit has a voltage of 24V and a current of 2A, what is the resistance?
Using Ohm's Law (R = V/I), R = 24V / 2A = 12 Ω.
Question 8 of 10
What is the resistance of a 60W, 12V light bulb?
Using R = V^2 / P, R = 12^2 / 60 = 144/60 = 2.4 Ω
Question 9 of 10
In an AC resistive circuit, how is resistance (R) calculated using impedance (Z) and reactance (X)?
In an AC resistive circuit, R = ?(Z² - X²).
Question 10 of 10
What is the relationship between power factor and resistance?
Resistance is often calculated by multiplying the power factor by the impedance.
