What is Ohm's Law?
Ohm's Law states that R = V / I.
Ohm's Law is I = V + R.
Ohm's Law defines power as P = I / R.
Ohm's Law is V = I * R.
State the formula for Ohm's Law.
V = R / I
V = I * R
R = V - I
I = V + R
If the voltage is 12V and the resistance is 4Ω, what is the current?
3A
4A
2A
6A
What unit is used to measure resistance?
ohms
volts
amps
watts
How does increasing resistance affect current, assuming voltage is constant?
Increasing resistance has no effect on current, assuming voltage is constant.
Increasing resistance increases current, assuming voltage is constant.
Increasing resistance causes current to fluctuate, assuming voltage is constant.
Increasing resistance decreases current, assuming voltage is constant.
What is the relationship between voltage, current, and resistance?
Voltage is independent of current and resistance.
Voltage, current, and resistance are related by Ohm's Law: V = I * R.
Resistance is the sum of voltage and current.
Current is the product of voltage and resistance.
If a circuit has a current of 3A and a resistance of 6Ω, what is the voltage?
18V
6V
12V
24V
What happens to the current if the voltage is doubled while resistance remains the same?
The current will decrease.
The current will remain the same.
The current will double.
The current will quadruple.
Can Ohm's Law be applied to non-linear components? Why or why not?
Ohm's Law is applicable to components with variable resistance.
No, Ohm's Law cannot be applied to non-linear components.
Yes, Ohm's Law applies to all components.
Ohm's Law can be applied if the component is at a constant temperature.
What is the significance of Ohm's Law in electrical engineering?
Ohm's Law only applies to AC circuits.
Ohm's Law is irrelevant for digital electronics.
Ohm's Law states that power is equal to voltage times current.
Ohm's Law is significant in electrical engineering as it provides a foundational relationship between voltage, current, and resistance, essential for circuit design and analysis.
