Follow the current Remember that we call a collection of connected electrical or electronic components a “circuit” because currents always flow from a source to a load and then back via a return ...

In a parallel circuit, if a lamp breaks or a component is disconnected, the other components continue working. This is because current continues to flow along remaining paths in the circuit.

Potential difference in series circuits Try the experiment online Resistors in series Test your knowledge Resistance ® close resistance (R)How difficult it is for current to flow. increases when ...

Circuits that supply current (using positive current flow convention) are usually known as a current source and one that limits the current flow on the ground side is known as a sink.

Draw a copy of the circuit diagram in your lab book. Use arrows to show the direction in which the current flows through the circuit. Label the input circuit and the output circuit of the ...

Knowing the deadly effects of resistance, voltage drop, and heat buildup, you should be careful choosing parts to be placed in a circuit exposed to high amounts of current flow.

Conventional current takes just the opposite direction, from the positive terminal, around the circuit and back to the negative terminal.

The effective ground-fault current path To understand the concept of bonding and grounding for safety, the installer must know that for normal load current, short circuit current, or ground-fault ...

Any current flow not equal to zero is a ground-fault. Depending on the impedance of the parallel neutral paths, the ground-fault protection relay may see current flow above its pickup point, causing ...

Despite their designed current-handling capacity, such circuits still need current limiters and circuit breakers to protect them from fault conditions.

Circuit breakers are a safety feature that automatically interrupts the flow of electricity in the face of a system fault or ...
