Answer:
Radius of the loop is 0.18 m or 18 cm
Explanation:
Given :
Current flowing through the wire, I = 45 A
Magnetic field at the center of the wire, B = 1.50 x 10⁻⁴ T
Number of turns in circular wire, N = 1
Consider R be the radius of the circular wire.
The magnetic field at the center of the current carrying circular wire is determine by the relation:
Here μ₀ is vacuum permeability constant and its value is 4π x 10⁻⁷ Tm/A.
Substitute the suitable values in the above equation.
R = 0.18 m
Answer:
Energy stored in the capacitor will be
Explanation:
We have given edge length of capacitor =
So area A = 1.2×1.2 = 1.44
Separation is given as d 1 mm =
We know that capacitance is given by
Voltage is given as V = 12 volt
We know that energy stored is given by
