Voltage is measured in volts (V) Current is measured in amps (A) Resistance is measured in ohms () Power is measured in watts (W) Electrical power, or the wattage of an electrical system, is always equal to the voltage multiplied by the current. In DC circuits, the voltages and currents are constant and do not vary with time as there is no sinusoidal waveform function related to the supply. 3. When a steady direct current flows through a coil, the only opposition to the flow of current is the resistance of the wire from which the coil is made. Because the resistor simply and directly resists the flow of electrons at all periods of time, the waveform for the voltage drop across the resistor is exactly in phase with the waveform for the current through it.
