Electrical Help at Your Fingertips

Ohm’s law is used in many branches of physics, including electricity, magnetism, and optics. It can be used to design electrical circuits, calculate power dissipation in electronic devices, and troubleshoot electrical problems. Read more.

Capacitors are used to store electricity. In contrast to the usefulness of resistors, capacitors do not dissipate energy in their optimal form. Read more..
 

Ohm’s law states that the current through a conductor between two points is directly proportional to the potential difference across the two points. In other words, the higher the voltage, the higher the current. Read more..

AC motors are more efficient than DC motors and can operate at higher speeds. Additionally, AC motors are less likely to overheat than DC motors and can be used in a variety of applications. Read more..
