what is the difference between over current and over voltage?

Over voltage is a condition that can damage insulation by increased electric field strength. Overcurrent is a condition that causes excess heat, caused by Joule heating in the conductors. Either can lead to failure of the device, but they are not the same.

Regulated – There is no variation in the output voltage of regulated power supplies irrespective of the current drawn by the load. ... Unregulated – The output voltage of unregulated power supplies changes with the output current, mainly because of the high internal resistance of the power supply.

A KVA is simply 1,000 volt amps. A volt is electrical pressure. An amp is electrical current. A term called apparent power (the absolute value of complex power, S) is equal to the product of the volts and amps.

Voltage is the electrical potential difference between two points while current is the flow of electric charge across a certain element. ... And just like water when given a path, the electrical potential would move from the point of higher potential to the point of lower potential until the two levels equalize.

Fundemantally one kVA is equal to 1,000 volt amps. Whereas a volt is for mesurement of electrical pressure an amp is a way of electrical current mesurement.

Originally Answered: What is the main difference in a voltage source and current source? voltage source is a source where the voltage “remains” constant.. A current source is an electronic circuit that delivers or absorbs an electric current which is Independent of the voltage across it.

Key Differences Between Short Circuit and Overload During the short circuit, the resistance of the path of current becomes low due to which the heavy current flow through the circuit whereas in overload condition the magnitude of the current is high but appreciably low as compared to short circuit current.

The main difference between AC and DC ground is that no current should flow into AC ground during normal operation, while all current should flow into DC ground. Current always needs a return path to its source. ... For DC systems, all current from supply rails returns to the source through DC ground.

There are several types of differences between the voltage and the current transformer. One of the major difference between them is that the current transformer converts the high value of current into low value whereas the potential or voltage transformer converts the high value of voltages into low voltage.

Switching capacity or switching load is usually rated with both voltage and current. The voltage is the load voltage which will be across the terminals of the relay when it is open. The current is the load current that will flow through both the load and relay when it is closed.

Current is the flow of charges. ... Hence, electric current is the flow of electrons in a circuit. It is directed from the negative terminal to the positive terminal. Conventional current on the other hand is the flow of positive charges and is directed from positive terminal of the battery to the negative terminal.

Voltage is directly proportional to current, so when the voltage doubles, the current is cut in half. Voltage is inversely proportional to current, so when the voltage doubles, the current doubles.

More specifically, circuit breakers and fuses are designed to detect when there is too much current in the circuit, while overload relays are designed to detect if a motor is overheating and will open the circuit if the motor gets too hot. For example, an overload relay can trip without a circuit breaker tripping.

Voltage and amperage are two measures of electrical current or flow of electrons. Voltage is a measure of the pressure that allows electrons to flow, while amperage is a measure of the volume of electrons.

In a simple sense, Volt is a unit of measuring voltage and watt is a unit of measuring power. Volt is the measure of potential difference which causes a current to flow through, having some resistance in the medium. While watt is the power released due to this potential difference and current.

A KVA is simply 1,000 volt amps. ... An amp is electrical current. A term called apparent power (the absolute value of complex power, S) is equal to the product of the volts and amps. On the other hand, a watt (W) is a measurement of real power.
