## Is Thevenin theorem applicable to AC and DC circuits?

Thevenin’s Theorem Statement Similar to the DC circuits, this method can be applied to the AC circuits consisting of linear elements like resistors, inductors, capacitors. Like thevinin’s equivalent resistance, equivalent thevinin’s impedance is obtained by replacing all voltage sources by their internal impedances.

**Is it possible to apply both theorems to AC as well as DC circuit?**

Maximum power transfer theorem can be applied to both DC and AC circuits, but the only difference is that the resistance is replaced with impedance in AC circuit.

**Can Thevenin’s theorem be applied to circuits having AC sources if yes then what will be the difference?**

Yes Thevenin theorem is applicable for AC circuit. The fact is that in DC circuit we use Thevenin equivalent resistance, but in AC we have to find the equivalent Impedance. In AC network we have to use phasor sum of the voltage sources .

### Does Thevenin work for AC?

Any combination of sinusoidal AC sources and impedances with two terminals can be replaced by a single voltage source e and a single series impedance z. The value of e is the open circuit voltage at the terminals, and the value of z is e divided by the current with the terminals short circuited.

**How do you verify Thevenin Theorem?**

- RL=VLIL. 3) Remove the load by opening the switch S2 and read the open circuit voltage (or Thevenin equivalent voltage) Vth.
- Rth=VI. 5) Now compute the load current.
- IL=VthRth+RL. 6) Compare the above computed load current with its observed value in step (2) and verify the theorem.

**Which theorem can be used for both linear and non linear circuits?**

Thevenin’s theorem: Any two terminal bilateral linear DC circuits can be replaced by an equivalent circuit consisting of a voltage source and a series resistor. Thevenin’s theorem can be applied to both AC and DC networks.

## How do you verify the reciprocity theorem?

In any branch of a network , the current (I) due to a single source of voltage (V) elsewhere in the network is equal to the current through the branch in which the source was originally placed when the source is placed in the branch in which the current (I) was originally obtained.

**Why Thevenin theorem is not applicable to nonlinear circuits?**

The fact is that in the DC circuit we use Thevenin equivalent resistance, but in AC we have to find the equivalent Impedance. In the AC network, we have to use the phasor sum of the voltage sources. All other conditions are similar to the DC source. Thevenin’s theorem cannot be applied to non-linear circuits.

**How do I verify Norton’s Theorem?**

Short the load terminals and find the short circuited current(Isc). Next, compute the resistance (Rint) of the network as seen from the load terminals, Replace the 220 V source by a short by closing s1 to “bb”. Apply V=110 V at the output terminals by closing s2 to “dd”.

### Can Thevenin’s theorem be applied to DC circuits?

Thevenin’s theorem can be applied to both AC and DC circuits. But it should be noted that this method can only be applied to AC circuits consisting of linear elements like resistors, inductors, capacitors. Like Thevenin’s equivalent resistance, equivalent Thevenin’s impedance is obtained by replacing all voltage sources with their internal

**What is Thevenin’s equivalent circuit?**

The Thevenin’s equivalent circuit consists of a series resistance of 6.67 Ω and a voltage source of 13.33 V. The current flowing in the circuit is calculated using the formula below: [latex]I=frac {V} {R}=frac {13.33,V} {6.67,Omega + 40,Omega}=0.286,A latex]&] Thevenin’s theorem can be applied to both AC and DC circuits.

**Is Thevenin’s theorem used in power system analysis?**

Thevenin’s theorem is used in the analysis of power systems. Is Thevenin’s Theorem applicable to non-linear circuits? No, Thevenin’s Theorem is not applicable to non-linear circuits. Is Thevenin’s Theorem applicable to AC circuits?

## How do I find the Thevenin source voltage and resistance?

Find the Thevenin source voltage by removing the load resistor from the original circuit and calculating the voltage across the open connection points where the load resistor used to be. Find the Thevenin resistance by removing all power sources in the original circuit…
