How is electromagnetic field strength calculated?

You can determine the magnitude of that force by plugging the dimensions and other properties of the magnet based into a simple equation: F = (n X i)2 X magnetic constant X a / (2 X g2).

How do you calculate electric field strength from voltage?

Since the voltage and plate separation are given, the electric field strength can be calculated directly from the expression E=VABd E = V AB d . Once the electric field strength is known, the force on a charge is found using F = qE.

How do you calculate electrical work?

So if 1 watt = 1 joule per second, it therefore follows that: 1 Joule of energy = 1 watt over one unit of time, that is: Work equals Power multiplied by Time, (V*I*t joules). So electrical energy (the work done) is obtained by multiplying power by the time in seconds that the charge (in the form of a current) flows.

What is the electric field strength at a distance of 10cm?

What is the electric field strength at a distance of 10 cm from a charge of 2 μC? So a one-coulomb charge placed there would feel a force of 180,000 newtons.

How do you calculate total electrical energy?

Electrical Energy = Power x Time. The total amount of electrical energy used depends on the total power used by all your electrical devices and the total time they are used in your home. One kilowatt hour is equal to 1000 watts of power used for one hour of time.

How do you find the electric field strength and distance?

The electrostatic force exerted by a point charge on a test charge at a distance r depends on the charge of both charges, as well as the distance between the two. The electric field E is defined to be E=Fq E = F q , where F is the Coulomb or electrostatic force exerted on a small positive test charge q.

What is the electric field n/c strength at a distance of 10 cm from a charge of 2 ΜC?

180,000 newtons
