The relationship between voltage and current is described by Ohm's Law, which states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the conductor. Mathematically, Ohm's Law can be expressed as:
V = I * R
Where:
V = Voltage (in volts)
I = Current (in amperes)
R = Resistance (in ohms)
This means that if the voltage across a conductor is increased, the current flowing through it will also increase, assuming the resistance remains constant. Conversely, if the voltage is decreased, the current will decrease as well. This relationship is fundamental in understanding and analyzing electrical circuits and devices.

Ohms Law:
The relationship between voltage (V), current (I), and resistance (R) in a circuit is described by Ohm's law:
```
V = I - R
```
Voltage (V):
- Voltage is the electrical potential difference between two points in a circuit.
- It is measured in volts (V).
- Voltmeters are used to measure voltage.
Current (I):
- Current is the flow of electric charge through a conductor.
- It is measured in amperes (A).
- Ammeters are used to measure current.
Resistance (R):
- Resistance is the opposition to the flow of electric current.
- It is measured in ohms (Ω).
- Ohmmeters are used to measure resistance.
Relationship:
Ohm's law states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to the resistance of the conductor.
- Directly proportional to voltage: If the voltage is doubled, the current will also double, assuming the resistance remains the same.
- Inversely proportional to resistance: If the resistance is doubled, the current will be halved, assuming the voltage remains the same.
Graphical Representation:
The relationship between voltage and current can be graphically represented by a straight line passing through the origin. The slope of the line represents the resistance of the circuit.

- Calculating power consumption
- Troubleshooting electrical devices
- Understanding the operation of various electronic components
