Certificates of deposit, or CDs, are fixed income investments that generally pay a set rate of interest over a fixed time period.
When referenced to the local common or ground, a common-mode signal appears on both lines of a two-wire cable, in-phase and with equal amplitudes. Technically, a common-mode voltage is one-half the vector sum of the voltages from each conductor of a balanced circuit to local ground or common.
That's what Ohm's law describes. Ohm's law is often written as V=IR, but it is probably more intuitively understandable if you write it V/R = I. Voltage and Resistance are the independent variables, the current is the dependent variable. If you increase the voltage, the current increases proportionally.
