WebAn electric circuit is capable of transferring power. Current is the rate of flow of charge, and voltage measures the energy transferred per unit of charge. We can insert these definitions into the equation for power: Electrical power is the product of voltage times current. in … WebAug 15, 2013 · The system’s maximum signal is generally 20 mA because this amount of current conveniently converts to a 5 V level with the selection of a suitable sense resistor, with 4-20 mA producing the 1 V to 5 V commonly used for metering and control circuits. A 250-Ω foil resistor is often used as the sense resistor in the current loop.

We know from Ohm’s Law that when a current flows through a resistance, a voltage is dropped across it producing a product which relates to power. In other words, if a resistance is subjected to a voltage, or if it conducts a current, then it will always consume electrical power and we can superimpose these three … See more Wirewound power resistors come in a variety of designs and types, from the standard smaller heatsink mounted aluminium body 25 Watt types as we have … See more What is the maximum power rating in watts of a fixed resistor which has a voltage of 12 volts across its terminals and a current of 50 milliamperes flowing … See more Calculate the maximum safe current that can pass through a 1.8KΩ resistor rated at 0.5 Watts. Again, as we know the resistors power rating and its resistance, … See more WebA resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias … code that runs when an unhandled error occurs
