An R-L circuit has a 60 V battery, a 42 H inductor, a 24 ohm
resistor, and a switch S, in series, as shown. Initially, the
switch is open, and there is no magnetic flux in the inductor. At
time the switch is
closed. In Figure 21.23b, when the resistor voltage is equal to the
inductor voltage, the current in the circuit is closest to:

A seven segment decoder is a digital circuit that
displays an input value 0 through 9 as a digital output in the
7-segment display. The behavior of this design can be modeled with
the schematic diagram below, where DCBA is the 4-bit input (D is
the most significant bit and A is the least significant bit) and
abcdefg is the 7-segment output.
