The same potential difference is applied across two wires. Wire A carries twice thecurrent of wire B. If the resistance of wire B isR, what is the resistance of wire A?

R / 2

Explanation:

According to Ohm law, the current flowing within the resistor is the ratio between the potential difference and the resistance:

So if wire A carries twice the current of wire B, while their potential is the same then:

the given statement is true.

sensory memory lasts for a fraction of seconds before the information is lost. it is the shortest -term memory and can be called as an element of memory. example: when we look at something and remember what it looks like, is just a second of observation. it degrades very quickly. it can also be considered as the process of perception rather than considering it as a memory.
