If a nichrome wire has a resistance of 15ω and is connected across the terminals of a 3.0 v flashlight battery, how much current is in the wire? 1.0 amps 5.0 amps 7.5 amps 0.20 amps

0.20 A

Explanation:

The current in the wire is given by Ohm's law:

where

I is the current

V is the voltage

R is the resistance

In this problem,

V = 3.0 V is the voltage

is the resistance

Substituting into the formula,

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
