The charge leaving the positive reference terminal of a voltage source isq(t)= [6sin120pi*t - 8cos120pi*t]mC
the voltage source value is v(t)= 160cos120pi*t V.
A) Determine the power supplied by the voltage source at t=0
B) Determine the energy supplied by the voltage source during the time period between t=0 and t=1/60 s.
a) What current will flow in the diode if the forward voltage bias is raised to 0.8V b) What current will flow in the diode if the forward voltage bias is lowered to 0.6V c) What change in forward bias voltage will increase the diode current by a ..
