Calculator and all Formulas Resistance (ohms), current (amps), and voltage (volts) Ohm's Law is the linear proportionality between current and voltage that occurs for most conductors of electricity. A graph of voltage against current is a straight line. The gradient is the resistance. Practition...
If there were only constant DC flow in the PDN interconnects from the VRMs to the ICs, that would cause a constant voltage drop, called the IR Drop, between the VRM and the ICs: IR Drop = (Series resistance of the power and ground rails) X (Current in the rails) ……… (PI-1) ...
