What is the relationship between voltage and current in Ohm's Law?
Voltage is directly proportional to current.
Voltage is independent of current.
Voltage is inversely proportional to current.
Voltage and current are unrelated.
If the voltage is 12 volts and the resistance is 4 ohms, what is the current?
4 amps
2 amps
6 amps
3 amps
Define resistance in the context of Ohm's Law.
Resistance is the speed at which current flows.
Resistance is the total amount of power consumed in a circuit.
Resistance is the opposition to the flow of electric current, defined by Ohm's Law as R = V/I.
Resistance is the measure of voltage in a circuit.
How does increasing resistance affect current if voltage remains constant?
Increasing resistance increases current if voltage remains constant.
Increasing resistance decreases current if voltage remains constant.
Increasing resistance causes current to fluctuate unpredictably if voltage remains constant.
Increasing resistance has no effect on current if voltage remains constant.
What is the formula for calculating resistance?
R = V + I
R = V * I
R = V / I
R = I / V
In a circuit with a current of 3 amps and a voltage of 9 volts, what is the resistance?
6 ohms
9 ohms
3 ohms
1 ohm
List one practical application of Ohm's Law in everyday life.
Calculating the current draw of household appliances.
Measuring voltage in a circuit.
Calculating the power output of a generator.
Determining the resistance of a wire.
How can Ohm's Law be used to determine the voltage drop across a resistor?
Use the formula V = R / I to calculate the voltage drop across a resistor.
The voltage drop can be found by adding the resistance and current values together.
Use the formula V = I * R to calculate the voltage drop across a resistor.
Ohm's Law states that voltage drop is equal to the total power consumed by the resistor.
What happens to the current if the voltage is doubled while resistance remains the same?
The current will quadruple.
The current will remain the same.
The current will double.
The current will decrease.
Explain how Ohm's Law applies to series circuits.
