Determine the rate of change of the current in the coils with inductance L = 0.4 H, if the induced EMF at its terminals during the time ∆t = 0.3 s E = 300 mV.
These tasks: L (inductance of the taken coil) = 0.4 H; ε (EMF induced at the terminals of the coil) = 300 mV (0.3 V); Δt (time change) = 0.3 s.
The rate of change of the current in the coil taken can be expressed from the formula: ε = | L * ΔI / Δt |, whence ΔI / Δt = ε / L.
Calculation: ΔI / Δt = 0.3 / 0.4 = 0.75 A.
Answer: The rate of change of the current in the coil is 0.75 A.
