Should not there be R (resistance) instead of I (current)in the last line i.e
I ∝ m/a^2
If this is an electrical question, there's something missing from that final line...gracy said:View attachment 82545

Yes,It is.XZ923 said:If this is an electrical question,

The answer is actually very similar to the one I posted in your previous thread...gracy said:What's that?

The relationship between resistance and current is described by Ohm's Law, which states that current is directly proportional to voltage and inversely proportional to resistance. In other words, as resistance increases, current decreases, and vice versa.
The equation I ∝ m/a^2 represents the relationship between current (I) and resistance (m/a^2). This means that as resistance increases (m/a^2), current decreases (I). It also implies that current is directly proportional to the inverse of resistance (1/m) squared.
Resistance affects current by impeding the flow of electrons through a circuit. The higher the resistance, the harder it is for electrons to flow, resulting in a lower current. Conversely, lower resistance allows for easier flow of electrons and results in a higher current.
The unit of measurement for resistance is the ohm (Ω), named after German physicist Georg Ohm. The unit of measurement for current is the ampere (A), named after French physicist André-Marie Ampère.
No, the relationship between resistance and current is not always linear. It follows Ohm's Law in most cases, but there are materials and circuits where this relationship is not linear. In these cases, the relationship may be described by other equations such as power laws or exponential functions.
