## What does E stand for in physics?

E. energy, total energy. J. joule. K, K_{t}, K_{r}.

## What is current formula?

The current formula is given as I = V/R. The SI unit of current is Ampere (Amp).

## What is U in physics class 9?

u is initial velocity. v is the final velocity. a is acceleration. t is the time period.

## What is the R in physics?

r = radius. R = resistance. R = molar gas constant.

## What is Ohm’s law state?

Ohm’s law states that the current through a conductor is proportional to the voltage across the conductor. V=IR where V is the voltage across the conductor and I is the current flowing through it.

## What is the power factor formula?

It is found by multiplying (kVA = V x A). The result is expressed as kVA units. PF expresses the ratio of true power used in a circuit to the apparent power delivered to the circuit.

## What is electricity formula?

Electrical energy is the product of power multiplied by the length of time it was consumed. In other words, Energy = power x time and Power = voltage x current. Therefore electrical power is related to energy and the unit given for electrical energy is the watt-seconds or joules.

## What does U mean in physics velocity?

Initial Velocity is the velocity at time interval t = 0 and it is represented by u. It is the velocity at which the motion starts.

## What is the symbol of density?

The symbol for density is the Greek letter rho, What is the density of a material if 450 cm ^{3} of it has a mass of 200 g?

## What is the full form of U in physics?

Answer: Full form of u in physics is upsilon..
