What is the resistance of a closed conductor if, when the magnetic flux penetrating it changes by 200 Wb for 10 s, an induction current of 4 A appears in the conductor?
ΔF = 200 Wb.
t = 10 s.
I = 4 A.
R -?
R = EMF / I – Ohm’s law for a closed circuit.
Faraday’s law of electromagnetic induction: EMF = ΔF / t.
Conductor resistance will be expressed by the formula: R = ΔF / I * t.
R = 200 Wb / 4 A * 10 s = 5 Ohm.
Answer: R = 5 ohms.
