The terms a.c. and d.c. stand for alternating current and direct current, respectively.
A dc load line is formed by joining the 2 points wherin the slope is equal to the inverse of the load resistance.. whereas the ac load lin has a different slope... and it intersects the dc load line at the quiescent point.
Both AC and DC are current methods in which electrons move along a wire
Kirchoff's Law is universally applicable, to AC as well as DC loops.
This statement is correct
DC load flow is a method to estimate power flows through lines on AC power systems. An accurate solution of the power flows on an AC system is a non-linear problem. Consequently it requires an iterative approach and there is no guarantee of reaching a "convergent" solution. A "DC" load flow uses a simplified, linear form of modeling the AC system. Consequently its solution is non-iterative, and absolutely convergent. It becomes a routine algebra problem, solving multiple equations with multiple variables. It is inherently less accurate than a "full" AC load flow solution, but it is useful where fast, dependable solutions are essential, and the approximation is acceptable. In reality, there is nothing "DC" about a DC load flow. It solves for phase angles (an AC, reactive characteristic); it ignores resistance (a DC characteristic); and it ignores voltage (because the objective is just power flow). It probably derives its name from the similarity between this solution method and the method used to solve a DC system, which is also linear, non-iterative and absolutely convergent.
well the difference mainly exists in the method of finding them , these are :-1. in finding DC load line :-open all AC sourcesopen all the capacitors2. for AC load line:-open all the Dc sourcesshort all the capacitors.
when the dc supply given, dc load line lies in the Ic and Vcc. when the AC supply given, AC load line lies in the Ic and Vcc.
KCL is Common to both AC and DC. Only the waveform or AC and DC will differ

The reason an AC voltage applied across a load resistance produces alternating current is because when you have AC voltage you have to have AC current. If DC voltage is applied, DC current is produced.
The dc load resistance is Rc but the AC Load resistance is (RcRl). If a load line is drawn the slope of which is -1(Rc Rl) . Then it is called an AC load line and it is to be used when the transistor is operating as an amplifier.
depends on your load...
The Synchronous motors will operate at a constant speed from noload to fullload. Even it is classified as an AC motor, we have to fed the motor both AC and DC supplies. That we have to supply DC to the Field (Normally Rotor) and AC to the Armature (Normally Stator).
WHEN YOU STEP UP THE VOLTAGE AND THE LOAD IS THE SAME MORE CURRENT WILL FLOW NOT LESS. AND THAT WILL HOLD TRUE FOR DC AS WELL. IF THE LOAD REMAINS THE SAME AND YOU INCREASE THE CURRENT AC OR DC THE VOLTAGE WILL INCREASE
Kirchoff's Law is universally applicable, to AC as well as DC loops.
