Complex impedance method for AC circuits
... an AC circuit driven by an external potential V = V0 cos ωt. The work done by the external potential in driving a charge q through a potential difference V is qV . Therefore the rate of doing work on the charges in a circuit, i.e. the power, is P = V dq/dt = V I. In an AC circuit, just as in a mecha ...

... So we can use a single resistor to replace the two resistors. The two 10 kΩ resistors have the same pair of nodes, hence they are in parallel. To combine the parallel resistors, we can take the reciprocal of the first resistance and take the reciprocal of the second one and add together, and then ta ...

Test probe
A test probe (test lead, test prod, or scope probe) is a physical device used to connect electronic test equipment to a device under test (DUT). They range from very simple, robust devices to complex probes that are sophisticated, expensive, and fragile.
