Hey Roopvrat,
The principles of voltage,current, and resistance measurement can be explained using electrons(charges):
- Voltage is the difference in charge between two points.
- Current is the rate at which charge is flowing.
- Resistance is a material's tendency to resist the flow of charge (current).
All this three quantities are related using Ohm's Law.
Ohm's law states that the electrical current (I) flowing in an circuit is proportional to the voltage (V) and inversely proportional to the resistance (R). Therefore, if the voltage is increased, the current will increase provided the resistance of the circuit does not change.
V = I . R
Thank You.
