# What is Ohm’s law called?

if a driver **physical states** For example, if the temperature, pressure, length and area remain constant, then the potential difference between its ends is equal to that of the flowing current. **proportional** it happens.

V I**V=IR **where R- is a constant.

R = V/I = Volt/Ampere = Ohm

#### Definition of 1 ohm

If a current of one ampere flows in a conducting wire, then a potential difference of one volt arises across its ends, then the resistance in that conductor wire will be. He **one ohm** Will be called

ie

If the value of current in a circuit is 1 ampere and the value of volt is also 1 ampere, then the value of its resistance will also be 1 ohm.

### graph between potential difference and current

By drawing a graph between the potential difference and current of a conductor, a straight line is obtained, which states that **potential difference** on the rise of **stream** will increase and the current will also decrease as the potential difference decreases.

### Limitations of Ohm’s Law

- driver’s
**distortion**do not arise - driver’s
**physical state**There should be no change in - This applies only to metals.

### Applications of Ohm’s Law

- Using Ohm’s law, a conductor wire
**resistance**is used to extract. - Using Ohm’s law,
**electronic circuit**In,**Regulator’s resistance**To control, in specific elements**voltage drop**is done to.

### examples of ohm’s law

**In one of the circuits, if 7A current is flowing and the resistance in the circuit is 5 ohms. Calculate the potential difference across the ends of the circuit.**

**solution:- ** Section (I) = 7 A

Resistance (R) = 5 ohm

Potential difference V= ?

**According to the formula, V = IR**

V = 5 × 7

** V = 35 volts**
