Taking a W light bulb connected to V, we estimate the resistance of the light bulb which changes with its temperature as The resistance of R can be arbitary kmemerly long as they resistances of each resistor is the same and the current rating is not exceeded. We require a capacitor that may be manually varied between and pF by rotation of a knob. Thus, the voltage across the 4. The voltage dropped across the 2.

This is again a non-inverting amplifier. This circuit does not require the supermesh technique, as it does not contain any current sources.

Analyze wide range of pure resistive DC circuits using the analyssis techniques covered through-out the course. We first determine the contribution of the voltage source: We decide to inject a 1-A current into the port: If the middle figure above corresponds to an angle of 0o and the case of perfect alignment maximum capacitance corresponds to an angle of o, we need to set out minimum angle to be 18o.

kemmdrly The best but not the only choice for a portable application is clear: The 5-A source supplies W, so it must therefore have a terminal voltage of 20 V. Mesh analysis will require the solution of three simultaneous mesh equations one mesh current can be found by inspectionplus several subtraction and multiplication operations to finally determine the voltage at the central node.

We may then write: Returning to the original circuit, we enginerring to perform nodal analysis to obtain VTH: Nodal equation at the op-amp output gives: We define four clockwise mesh currents. We proceed to find the contribution of the current source: Then KVL allows us to write: The V source supplies W, so it must therefore provide a current IX of Nodal analysis is probably best then- the nodes can be named so that the desired voltage is a nodal voltage, or, at worst, we have one supernode equation to solve.

As can be seen, a current of Define three clockwise mesh currents: Then by mesh analysis, define 4 clockwise mesh currents I1, I2, I3, I4 in the top left, top right, bottom left and bottom right meshes, respectively: This is the voltage across the capacitor when the second source kicks on.

Carry power consumption calculation for different components in a DC circuit. Making use of Eq.

Editoon should be noted that depending on the line fit to the experimental data, these values can change somewhat, particularly the series resistance value. We have a difference amplifier as the first amplifier stage, and a simple voltage follower as the second stage.

We choose the center node for our common terminal, since it connects to the largest number of branches.

The resistances are given by: At the b, c, d supernode: In order to determine which of these two values should be used, we must recall that the idea is to charge the battery, implying that it is absorbing power, or that i as defined is positive. Note that the switch properties were changed. It is now a straightforward matter to compute the power absorbed by each element: Thus, substituting these expressions into our four mesh equations and creating a matrix equation, we arrive at: KCL provides us with the means to find this current: This can be done by using a differential amplifier: Starting with the left-most mesh and moving right, we define four clockwise mesh currents i1, i2, i3 and i4.
