A parallel-plate capacitor, made of two circular plates of radius R = 10 cm, is connected in series with a resistor of resistance R = 100 Ω and a battery of emf E = 10 V. What is the maximum value of the magnetic field induced by the displacement current between the plates, at a distance r = 5 cm from the axis of the plates while the capacitor is being charged?

Explanation:

At the time when the capacitor starts charging , current through will be maximum .

Current in the circuit = 10 / 100 = .1 A .

This is called displacement current Id = .1 A .

magnetic field between the plates will be due to this displacement current .

Magnetic field lines  will be  circular in shape.

If B be the magnetic field , we shall apply ampere's circuital law to find magnetic field due to displacement current at a distance of 5 cm from axis.

∫ B dl = μ₀ Id

B x 2π x  .05  = 8.85 x 10⁻¹² x .1

B = 2.82 x 10⁻¹² T .

c. 7/3

step-by-step explanation:

a rational number is like pi- it is a repeating decimal.

a. is -1.8

b. 2.236068

c. 2.3333333333333333333

d.   is 3

i hope that ! =)

are there options? cause you ain’t. real specific
