The relationship between current and potential difference (PD) is described by Ohm's Law. Ohm's Law states that the current (I) flowing through a conductor is directly proportional to the potential difference (V) across it and inversely proportional to its resistance (R).
This is mathematically expressed as:
\[
I = \frac{V}{R}
\]
In simple terms:
In summary, the current depends on both the potential difference and the resistance. A higher PD results in more current, and higher resistance results in less current.
This is mathematically expressed as:
\[
I = \frac{V}{R}
\]
- I is the current (measured in amperes, A)
- V is the potential difference (measured in volts, V)
- R is the resistance (measured in ohms, Ω)
In simple terms:
- If the potential difference (PD) increases (while keeping resistance constant), the current will increase.
- If the resistance increases (while keeping the PD constant), the current will decrease.
In summary, the current depends on both the potential difference and the resistance. A higher PD results in more current, and higher resistance results in less current.
