Current Formula 2 (Power and Voltage) The power transferred is the product of supply voltage and electric current. Thus, we get current equals the power divided by voltage. Mathematically, Where stands for amperes or amps (the units for electric current). Example As shown in the circuit below...
Formula Application: To calculate the current through any branch in a parallel circuit, divide the total circuit current by the resistance of the branch, then multiply by the total resistance of the circuit. Derivation Insight: Understanding the derivation helps predict how currents distribute in comp...
charge per unit time) past a point in space. This charge is carried by electrons moving through a wire in an electric circuit. The higher the number of electrons moving past this point per second, the greater the magnitude of the current. ...
The peak-to-peak value of an AC waveform is a value measured from the positive peak to the negative peak. Voltages and currents in an AC circuit are sometimes given in their peak-to-peak values. Because a pure sine wave with an average value of zero has equal values above and below th...
Ohm's lawand the formula for power derived for dc circuits in the previous section also apply to the simple ac circuit shown inFigure 2-6. However,ac circuits are never so simple in real applications. The rms current in an ac circuit with resistance is given by the rms voltage divided ...

The current transformer consists of at least one converter core with a primary winding and at least one secondary winding, a burden resistance being connected parallel thereto and closing the secondary circuit with a low resistance. A closed annular core without an air gap is used as the ...
Gain in Current If the current flowing through a circuit is increased, the gain in current can be calculated using Ohm’s Law. The formula for calculating gain in current is: Gain in Current = Voltage / Resistance For example, if the voltage across a resistor is increased from 12 volts to...
