Definition of the SI Unit of Resistance
The SI unit of resistance is the Ohm (symbol: Ω). It is defined as the resistance between two points in a conductor when a constant potential difference of one volt applied across the conductor produces a current of one ampere. In simpler terms, an Ohm measures how much a material opposes the flow of electric current.
Calculation of Resistance
To calculate the resistance of a resistor using Ohm's Law, we use the formula:
Resistance (R) = Voltage (V) / Current (I)
Where:
- Voltage (V) is the potential difference in volts (V).
- Current (I) is the flow of electric charge in amperes (A).
Given Values
- Current (I) = 200 mA = 0.2 A (since 1 A = 1000 mA)
- Voltage (V) = 0.8 V
Plugging in the Values
Now, substituting the given values into the formula:
R = V / I
R = 0.8 V / 0.2 A
Calculating Resistance
Performing the calculation:
R = 4 Ω
Conclusion
The resistance of the resistor is 4 Ohms. This means that it opposes the flow of electric current, allowing a specific amount of current to pass through when a certain voltage is applied. Understanding resistance is crucial for analyzing electrical circuits and ensuring they function correctly.
