A1.5m wire carries a 2 a current when a potential difference of 59 v is applied. what is the resistance of the wire?

We can use the relation of ohm's law to find out the resistance of wire

given that

V = 59 volts

i = 2 A

now as per above formula

So resistance of wire is 29.5 ohm.

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
