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

- Current should be directly proportional to the voltage
- Current should be inversely proportional to the resistance
- Voltage should be directly proportional to the resistance
- Both A and B

**Answer:** Option(D)

**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** ?

- Ohm’s law is valid for non-linear circuit only
- Ohm’s law is valid for linear circuit only
- Ohm’s law is valid for both linear and non-linear circuit
- Ohm’s law is valid for unilateral circuit only

**Answer:** Option(B)

**Memory:** No information is available.

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

- Temperature should remain constant
- Voltage should remain constant
- Current should remain constant
- Power should remain constant

**Answer:** Option(A)

**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 |

**Answer:** Option(B)

**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** ?

- Capacitance
- Inductance
- Resistance
- Transistor

**Answer:** Option(C)

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

## 6.** Ohm’s law applicable to** ?

- Linear circuit only
- Non-linear circuit only
- unilateral circuit only
- All of the above

**Answer:** Option(A)

**Memory:** Ohm’s law is applicable to circuits containing linear elements only.

Such as, **resistance**, **capacitance**, **inductance**.

Because, these elements show linear output characteristics (whose output graph is a straight line

).
