Your friend says that according to Ohm’s law, high voltage produces high current. Then your friend asks, ""So how can power be transmitted at high voltage and low current in a power line?"" What is your illuminating response?

Explanation:

According to Ohm's law the current is directly proportional to the voltage between two points and inversely proportional to the resistance.

Mathematically:

where:

current

voltage

resistance

here resistance is a constant and cannot be changed, so:

hence for this ratio to be constant the values of voltage and current adjust accordingly.

We have the expression for the power as:

for a particular energy source the energy remains conserved.

so, on increasing Voltage the current will reduce to compensate the energy conservation.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
