WebI3 - current of load #3 in amps (A). Current divider The current division of resistors in parallel is RT = 1 / (1/ R2 + 1/ R3) or I1 = IT × RT / ( R1 + RT) Kirchhoff's current law (KCL) The junction of several electrical components is called a node. The algebraic sum of currents entering a node is zero. ∑ Ik = 0 Alternating Current (AC) WebObtaining sinusoidal expression. I have the question " The instantaneous values of two alternating currents are given by i1 = 20sinwt amperes and i2 = 10sin (wt + pi/3) amperes. By plotting i1 and i2 on the same axes, using the same scale, over one cycle, and adding ordinates at intervals, obtain a sinusoidal expression for i1 + i2."

WebNov 30, 2015 · Your answer is correct, but only because sin ( x) = sin ( x + 2 π). L ( sin ( 2 t) u π ( t)) = e − π s ⋅ L ( sin ( 2 ( t + π))) = e − p i s ⋅ L ( sin ( 2 t + 2 π)) = e − π s ⋅ L ( sin ( 2 t)) = e − π s ⋅ 2 s 2 + 4 Share Cite Follow answered Nov 30, 2015 at 3:54 Christopher Carl Heckman 4,420 14 20 )) e − c s ⋅ L t + c)). Nov 30, 2015 at 4:10 Websin α = side opposite hypotenuse and cos β = side adjacent hypotenuse. Notice that the side adjacent to β is the same as the side opposite of α, thus sin α = cos β. In addition, since this is a right triangle, α + β = π 2. So we can make a substitution for β = π 2 − α to say that sin α = cos ( π 2 − α) Share Cite Follow edited Apr 1, 2014 at 22:06 Web2.
