## 1. Which of the following is true regarding Ohm’s law statement ?

1. Current should be directly proportional to the voltage
2. Current should be inversely proportional to the resistance
3. Voltage should be directly proportional to the resistance
4. Both A and B

Memory: Almost every student has familiar with the term Ohm’s Law.

That describes the relationship between Voltage, Current and Resistance

.

This law was named after the German Physicist Georg Simon Ohm.

According to this law,

If temperature and other environmental conditions remain constant, Current flowing through a conductor between two points is directly proportional to the potential difference(Voltage) across the points and inversely proportional to the resistance of the circuit.

## 2. Which of the following is true regarding limitation of ohm’s law ?

1. Ohm’s law is valid for non-linear circuit only
2. Ohm’s law is valid for linear circuit only
3. Ohm’s law is valid for both linear and non-linear circuit
4. Ohm’s law is valid for unilateral circuit only

Memory: No information is available.

## 3. Condition for Ohm’s law is that –

1. Temperature should remain constant
2. Voltage should remain constant
3. Current should remain constant
4. Power should remain constant

Memory: Condition for ohm’s law is temperature and other environmental conditions should remain constant.

## 4. Which of the following equations describe vector form of ohm’s law ?

 A. B. C. D. None of the above

Memory: Vector form of ohm’s law typically used in electromagnetic and material science for finding current density, conductivity, and electric field.

This reformatting of ohm’s law generally takes place due to a German physicist Gustav Robert Kirchhoff.

## 5. Ohm is the unit of ?

1. Capacitance
2. Inductance
3. Resistance
4. Transistor

Memory: Ohm is the both practical and SI unit of resistance.

## 6. Ohm’s law applicable to ?

1. Linear circuit only
2. Non-linear circuit only
3. unilateral circuit only
4. All of the above
