# ELI the ICE man, who lives in a cave with AC

ELI on ICE, who lives in ACave, helps you ride the electromagnetic wave.

ELI the ICE Man, who lives in a cave,
Knows how inductors and capacitors behave.
Determining their phases is his favourite game.
If you ever think Help! Just call out his name.

What is the relationship between power (watts/volts) and frequency?

In AC their are 3 calculated powers which are Apparent power, Real power and Reactive power. Real power is not affected by frequency. On the other hand Apparent, and reactive power are affected by frequency. Inductive or capacitive reactance equals 2 pi f L or 1/( 2 pi f C) respectively. You should also take note of Eli the Ice man to know what’s lagging and leading.

The current through inductors lag, you can tell,
Because when you spell ELI, I is after L.
When you look at ICE, you will see,
The current of a cap leads; I is before C.
If you spell out his name, E is in sight,
But we do not talk about voltage relationships,
It’s impolite.

... This leads to a positive phase for inductive circuits since current lags the voltage in an inductive circuit. The phase is negative for a capacitive circuit since the current leads the voltage. The useful mnemonic ELI the ICE man helps to remember the sign of the phase. The phase relation is often depicted graphically in a phasor diagram.

When a voltage is applied to an inductor, it resists the change in current. The current builds up more slowly than the voltage, lagging in time and phase.

Since the voltage on a capacitor is directly proportional to the charge on it, the current must lead the voltage in time and phase to conduct charge to the capacitor plates and raise the voltage.

But we do not talk about that phase in the relationships,
It’s impolite.

ELI the ICE man or ELI on ICE – the voltage E leads the current I in an inductor L; the current leads the voltage in a capacitor C.

Another common mnemonic is CIVIL – in a capacitor (C) the current (I) leads voltage (V), voltage (V) leads current (I) in an inductor (L).

### Earth's AC and DC global electrical circuits

The not so Recent progress on the global electrical circuit paper in 2014 mentions Alternating Current and Direct Current circuits in our planets atmospheric and solar system circuitry:

• Electrified shower clouds (without lightning) contribute to the DC global circuit.
• The DC and AC global circuits are natural frameworks for investigating global change.

Are they AC or DC, or steady state Direct Current and Alternating Current planets and Electric Universe? Is there no such thing as human measured DC, is it all AC or flow or no total flow? Potentials of differences.

### Inductive and Capacitive

Reactance, in electricity, measure of the opposition that a circuit or a part of a circuit presents to electric current insofar as the current is varying or alternating. Steady electric currents flowing along conductors in one direction undergo opposition called electrical resistance, but no reactance. Reactance is present in addition to resistance when conductors carry alternating current.

Reactance also occurs for short intervals when direct current is changing as it approaches or departs from steady flow, for example, when switches are closed or opened.
Reactance - Electronics | Encyclopaedia Britannica

Reactance is of two types: inductive and capacitive. Inductive reactance is associated with the magnetic field that surrounds a wire or a coil carrying a current. An alternating current in such a conductor, or inductor, sets up an alternating magnetic field that in turn affects the current in, and the voltage (potential difference) across, that part of the circuit. An inductor essentially opposes changes in current, making changes in the current lag behind those in the voltage.
Reactance - Electronics | Encyclopaedia Britannica

Earth's and planets atmospheres and geology - telluric currents, layer upon different layer of spheres of electromagnetically excited elements surrounding our globe and potentially in our geology, equatorial plasma jets, 40 lighting strikes per second between dielectric layers of Earth's global electric circuit (over 1 billion plasma discharges each year).

Capacitive reactance, on the other hand, is associated with the changing electric field between two conducting surfaces (plates) separated from each other by an insulating medium. Such a set of conductors, a capacitor, essentially opposes changes in voltage, or potential difference, across its plates. A capacitor in a circuit retards current flow by causing the alternating voltage to lag behind the alternating current, a relationship in contrast to that caused by an inductor.

The capacitive reactance, a measure of this opposition, is inversely proportional to the frequency f of the alternating current and to a property of the capacitor called capacitance

AC/DC EU?

One important point to keep in mind, is that when current flows through a purely resistive circuit, the voltage and current arrive at the same point at the same time. In other words, Voltage and Current are in phase in a purely resistive circuit.

In a circuit which contains inductance or capacitance though this is not so. In an inductive circuit, the voltage leads the current by 90 degrees (assuming a purely inductive circuit).

Likewise, in a capacitive circuit, the current leads the voltage by 90 degrees. Which leads which is easy to remember.

Just think "Eli the Ice man".
ELI Inductive circuit...... Voltage arrives before Current .
ICE Capacitive circuit... Current arrives before Voltage.

E=Voltage
I=Current
L=Inductor
C=Capacitor
