In circuits connected in parallel, the components are connected on different branches. Find out more with BBC Bitesize. For students between the ages of 11 and 14.

An integrator that you configure with an op amp is a simple circuit consisting of a resistor, a capacitor, and an op amp, so how can anything go wrong? In Figure 1, when Z F is a capacitor, the closed ...

If you perform analog-circuit design, you'll occasionally need to use a resistor with a nonstandard value to produce a particular gain, ratio, or attenuation factor. You can create resistors of ...

Pi network attenuator circuit. SpinningSpark (CC BY-SA 3.0). A Pi network attenuator is a simple three-resistor circuit, as shown in the diagram to the right.

Norton's theorem Norton's theorem, related to Thevenin's, states that a complex linear circuit can reduce to an equivalent current source and parallel resistor. This is the dual of Thevenin's ...
