Your gadgets run on direct current, but the electricity in your home is alternating current. What’s up with that?

We've talked about AC Circuits, but now it's time to delve into the world of AC Circuits (or Alternating Currents). We’ve talked about how they change voltage, which helps transmit electricity ...

Like most other simple circuits, this circuit also has a disadvantage: It is incompatible with some load-power and ac-mains-voltage values. When a fuse burns out, the load stays connected to the ac ...

SMPS circuits offer an efficient way to reduce AC from a mains source to any desired level for powering low-voltage circuits, though this comes at the cost of components such as control ICs, switching ...

Voltage and current sine waves are in-phase when they peak and cross the zero axis at the same time. However, this rarely happens and only in AC circuits containing pure resistances. Most AC circuits ...

The situation in ac circuits is more complicated because current typically lags the voltage. This relationship enters into power calculations and also can lead to some misunderstandings about ...
