Current in resistor formula
WebDec 5, 2015 · The Ohm's law formula can be used to calculate the resistance as the quotient of the voltage and current. It can be written … WebConductance measures how easy it is for electric current to flow and is the inverse of resistance. Conductance is symbolized by the letter “G” and is measured in units of siemens or mhos. The concept and measurement units of resistance are most often used when describing the relationship of current flow to voltage through Ohm’s Law .

WebIt is possible to replace a series of a resistor with an equivalent resistor. Also, the equivalent resistance of the number of resistors in a series is the sum of the individual resistance values. Besides, the unit of resistance is … WebWhat is the current in the resistor? Using Ohm's Law, i = v/R gives us i = (A sin wt) / R. So when the voltage is a sinusoid, the current is a sinusoid, too. In general, if you define either v or i to be sinusoidal, the other will follow along and be sinusoidal, too. In a resistor, the sinusoidal i and v are lined up with each other in time.
