Electrical questions, answered by experts

A light switch can stop working for several reasons. Typical causes include a blown fuse or tripped circuit breaker, both of which shut off power to the switch. Worn-out or faulty internal switch components can also prevent it from functioning properly. Loose or disconnected wiring within the switch or electrical box is another frequent issue. Additionally, switches may fail due to age, excessive use, or physical damage. In some cases, problems with the light fixture or bulb itself might be mistakenly attributed to the switch.

No, because amps and volts measure very different things. However, you can use basic equations to find amps or volts by using data about one of the measurements to calculate the other.

Timers work by using an internal switch to turn power on or off to the cord plugged into it. Just the same way that a light switch turns lights on and off, the timer throws the switch at the programmed times.

The easiest and best way to power your outdoor lights is with the use of outdoor outlets. Most building codes now require exterior outlets in homes, so you likely already have outdoor outlets available to plug into. However, you can have these outlets installed if your space doesn’t currently include them.

Watts and volts represent distinct aspects of a light bulb’s functionality. Volts measure the electrical force that drives the current through the bulb, determining its compatibility with the power source. Watts, on the other hand, quantify the bulb’s power consumption and indicate its brightness level. Higher watts generally mean a brighter bulb.
