Answer:
I = 5000 A
Explanation:
We will use Ampere's Law to calculate the current:
where,
B = Magnetic Field Strength = 0.1 mT = 1 x 10⁻⁴ T
μ = Permeability of Free Space = 4π x 10⁻⁷ N/A²
I = Current = ?
r = radius = 10 m
Therefore,
<u>I = 5000 A</u>
Answer:
<h2><u>Rheostat:</u></h2>=> Rheostat is an electric device used as a variable resistance, like the regulator of the fan. It is used to change the electric resistance in the electric circuit.
<h2><u>Principle / Rule:</u></h2>=> Rheostat works on the principle of Ohm’s law. Ohm’s law states that current in a circuit is inversely proportional to the resistance at the given temperature.
