  • Q1
    What does Ohm's law state?
    Electrons flow from negative to positive terminal.
    Voltage equals current multiplied by resistance.
    The current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to its resistance.
    Resistance remains constant with temperature.

  • Q2
    What is the formula for Ohm's Law?
    I = V / R
    V = I * R
    R = V * I
    V = R + I

  • Q4
    What is the relationship between voltage and current according to Ohm's law?
    The current flowing through a conductor is independent of the voltage applied across it.
    The current flowing through a conductor is directly proportional to the voltage applied across it.
    The current flowing through a conductor is equal to the voltage applied across it.
    The current flowing through a conductor is inversely proportional to the voltage applied across it.
