I.43 [See also R.22, R.48, I.43, S.44.] The network of resistors considered in R.22 was later
determined to have self-inductance L = 11 µH. Compute the value of the inductive time
constant for this circuit.
I.44 [See also R.27, S.42.] The network of resistors studied in R.27 was later found to
possess self-inductance L = 0.5 H. Compute the value of the inductive time constant for this
circuit.
I.45 [See also S.57.]
A transformer consists of a ferrous core around
which are wrapped two coils, designated the
primary and the secondary. The core effi-
ciently channels magnetic flux from one coil
to the other. In an ideal transformer ...
