Ohm’s Law: The Basics

Ohm’s Law states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points, and inversely proportional to the resistance between them. It can be expressed mathematically as: I = V / R Where: I = current (measured in amperes, A) V = voltage (measured in …

IDMT Relay Tripping Time Calculator

An IDMT (Inverse Definite Minimum Time) relay is a type of protective relay that is used to provide overcurrent protection for electrical systems. IDMT relays are commonly used in low-voltage and medium-voltage electrical systems to protect against overcurrents caused by fault conditions such as short circuits. IDMT relays work by monitoring the current flowing through …

Amps to Kilowatts Calculator

During electrical power calculation, typically we use the normal calculator, in which sometimes we make mistakes during ac power calculations. Ac power consists of a power factor which we have to take into consideration. Again for three phase we have consider root 3 facor. This simple calculator will reduce the possibility of making an error …
