A constant inductance of one henry and a variable
resistance R are connected in series with a constant
e.m.f. of E volts. If R = 1/(1+t) at time t seconds
and if the current is initially zero, what value of E will
make the current 24 amperes after 4 seconds?
Suppose that the resistance is 12 ohms and the inductance is 4H, and a generator that produces a variable voltage of: E(t) = 60sin30t volts with no initial current. Find
the amount of current after 20 seconds.
Note: Make sure your calculator is in RADIAN mode since it involves a trigonometric function.

O 3.68 A
O 5.65 A

5. 18 Volt battery is connected to a series in which the inductance L=1/4 henry and the resistance is R=8 ohms. Solve
the first order equation is given as L+ Ri = V to determine the current i(t) if the initial current is zero (i(0)=?).
