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...
1.Five common units used in working with electricity and electric circuits are the volt,ampere,watt,ohm,and hertz.2.The relationship of voltage(in volts) to current (in amperes) and resistance (in ohms) is expressed by ohm's Law:Voltage=current X resistance....
Define resistivity and state its units. How is horsepower related to the SI unit of power? Define kilowatt-hour and state its value in SI unit? Explain the property of electric current. Define average power and write its S.I. Unit. ...
When measuring electric current with a digital multimeter, you must set the instrument to its current function before making measurements. The instrument will have a number of display units, for example μA, mA, and A, so you’ll need to select the measurement range that best suits the curre...
The S.I system of units has the fundamental units of length, mass and time as meter (m), kilogram (kg) and second (s). On the same system, the amount of a substance has a unit called the mole, and temperature has the kelvin (K) as its unit....
