The power factor of an AC circuit is defined as the ratio of the real power (W) consumed by a circuit to the apparent power (VA) consumed by the same circuit. This therefore gives us: Power Factor = Real Power/Apparent Power, orp.f. = W/VA. What does apparent power mean? :the p...
When you get an electric shock, it interrupts the normal operation of the system, sort of like a power surge. A shock at the lightning level can cause your body to stop. The electrical process doesn't work anymore — it's fried. But that’s a story for another time. Human Body Makes...

Find Pros Now + Q: When I plugged my cell phone charger into a kitchen outlet, my phone didn’t start charging—the electrical outlet was not working. Is there something I can do to fix the outlet myself, or should I call an electrician?
How to Design a Circuit Board: An Introduction A common mistake of amateur layout designers is racing to get to the board level of design. It’s not hard to understand why: the board is the fun part of the design, where users play a 3D puzzle game trying to find the best-engineered ...
Power is a measure of the rate of work. Per the physics law of conservation of energy, the power dissipated in the circuit must equal the total power applied by the source(s). Therefore, an interesting rule for total circuit power versus individual component power is that it is additive fo...
Circuit includes a configuration sequential logic with a predetermined state that needs to be stored before the circuit enters the standby mode. The mobile device further includes a power-down unit which significantly reduce the standby current can be stored in the storage region of low leakage ...
The operating system can send a signal to the power supply to tell it to turn off. The push button sends a 5-volt signal to the power supply to tell it when to turn on. The power supply also has a circuit that supplies 5 volts, called VSB for "standby voltage" even when it is ...
