- Q1What 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.30s
- Q2What is the formula for Ohm's Law?I = V / RV = I * RR = V * IV = R + I30s
- Q3What is the unit used to measure resistance?Volt (V)Ampere (A)Joule (J)Ohm (Ω)30s
- Q4What 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.30s
- Q5What is the SI unit of electric current?Coulomb (C)Ohm (Ω)Ampere (A)Volt (V)30s
- Q6What is the formula to calculate resistance using Ohm's law?R = V * IR = V / IR = V + IR = I / V30s
- Q7Which of the following quantities is measured in Ohms?ResistanceVoltagePowerCurrent30s
- Q8What does the symbol 'V' represent in Ohm's law?VoltageCurrentPowerResistance30s
- Q9What is the symbol used to represent electric current in Ohm's law?IVRP30s
- Q10Which variable in Ohm's law is directly proportional to resistance?VoltageEnergyPowerCurrent30s
