What is an ampere sign?

The ampere (SI unit symbol: A; SI dimension symbol: I), often shortened to Amp, is the SI unit of electric current (quantity symbol: I,i) and is one of the seven SI base units. It is named after André-Marie Ampère (1775–1836), French mathematician and physicist, considered the father of electrodynamics.

Which of the following represents the unit of electric energy?

So watt sec represents the unit of energy.

Which is largest unit of energy?

Joule

Which is largest amount of energy?

Convert electron-volt, erg and calorie to joule and find out which of the following has the highest value. Thus, the highest value is 4.18 joule. Thus, the unit that represents the largest amount of energy is calorie.

Which is the following represents voltage?

As W=VIt,V=WI×t, i.e.,Voltage =Work donecurrent×Time.

What is the formula for calculating voltage?

Ohm’s law equation (formula): V = I × R and the power law equation (formula): P = I × V. P = power, I or J = Latin: influare, international ampere, or intensity and R = resistance. V = voltage, electric potential difference Δ V or E = electromotive force (emf = voltage).

Which one of the following formula indicate the voltage?

“Work × Time/Current” is formula represents the voltage.

How do you represent voltage?

Hence, voltage is represented as Voltage=Current×timeWorkdone.

What represents the voltage explain?

Voltage is the pressure from an electrical circuit’s power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light. In brief, voltage = pressure, and it is measured in volts (V).

What is the unit of EMF of a cell?

volts

What is the formula for back EMF?

The back emf is calculated based on the difference between the supplied voltage and the loss from the current through the resistance. The power from each device is calculated from one of the power formulas based on the given information. The back emf is ϵi=ϵS−I(Rf+REa)=120V−(10A)(2.0Ω)=100V.
