In National 4 Physics learn how the operation of switches and variable resistors allow us to control real circuits in the appliances around us.

This circuit contains a 5 Ω resistor in series with two resistors, 6 Ω and 4 Ω, which are in parallel. Start by calculating the combined resistance of the two parallel resistors.

Series-parallel circuit. The Figure at right shows three impedances; two are connected in parallel and then connected in series with a third impedance. Each impedance can be a pure resistance, a pure ...

Series and Parallel Circuit Series and parallel circuits are two fundamental configurations in electrical circuits, each with distinct characteristics that affect how electricity flows through them.

Fig. 3: Capacitors in series. You can also replace one capacitor by putting two capacitors in parallel as shown in Fig. 4. In this case, a .0015 mfd capacitor can be replaced by a .001 mfd and a .0005 ...

Overview A 6-V battery powers a circuit with parallel branches on a board. Several wires and light bulbs plug into the board to make various series and parallel circuits. The brightness of the bulbs ...

Solid-state dc circuit breaker (SSCB) has become a key component for fast fault isolation in high-voltage dc systems. However, their effectiveness often relies on complex series and parallel ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...
