A 1.35 V potential difference is maintained across a 1.1 m length of tungsten wire that has a cross-sectional area of 0.72 mm2 . What is the current in the wire? The resistivity of the tungsten is 5.6 × 10−8 Ω · m . Answer in units of A.

Therefore,

The current in the wire is 15.77 Ampere.

Explanation:

Given:

Length = l = 1.1 meter

V = 1.35 Volt

To Find:

Current, I =?

Solution:

Resistance for 1.1-m long tungsten wire with a cross sectional area, if it is connected across a 1.35 V potential difference given as

Where,

R = Resistance

l = length

A = Area of cross section

Substituting the values we get

Now by Ohm's Law,

Substituting the values we get

Therefore,

The current in the wire is 15.77 Ampere.

the answer is a. the yacht traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.

im doing peak rn so sry if its wrong

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
