Understanding Basic Electrical Theory

No single discovery has affected our lives, our culture and our survival more than electricity. Electricity is everywhere; it lights our way, cooks our food and can even brush your teeth. For an example, imagine where the medical field would be without electricity and in that sense how many lives have been saved due to electrical devices like defibrillators, pacemakers, etc.  From talkies to eight tracks to screaming “I want my MTV”, even hashtagging, none of it would be possible #WithoutElectricity. Read on to discover more about basic electrical theory.

What is Electricity?

So what is electricity and where does it come from? More importantly, why is carpet, socks and a doorknob a bad combination? In its simplest terms, electricity is the movement of charge, which is considered by convention to be, from positive to negative. No matter how the charge is created, chemically (like in batteries) or physically (friction from socks and carpet), the movement of the discharge is electricity.

Understanding Current

The most fundamental law in electricity is Ohm’s law or V=IR. The V is for voltage, which means the potential difference between two charges. In other words, it is a measurement of the work required to move a unit charge between two points. When we see a value such as 10 Volts, it is a measurement of the potential difference between two reference points. Normally the two points will be +10V and 0V (also known as ground), but it can also be the difference between +5V and -5V, +20V and +10V, etc. In the field, you might hear the term “common grounds” which refers to each device in a system using the same zero-point reference (or ground) to ensure the same potential difference ( or voltage) is applied throughout the system. The next component of Ohm’s law is current, the units of which are Amperes; in the formula, current is represented by the very logical choice of the letter I. As mentioned previously, current is the measurement of the flow of charge in a circuit. This leaves us with the letter R which represents Resistance. Electrical resistance, measured in Ohms, is the measure of the amount of current repulsion in a circuit. Simply, resistance resists current flow. When electrons flow against the opposition offered by resistance in the circuit, friction occurs and heat is produced. The most common application for resistance in a circuit is the light bulb. The light bulb introduces enough resistance in a circuit to heat up the filament inside, causing light to be emitted. Resistance in a circuit can also be helpful when needing to alter voltage levels, current paths, etc. Resistors are self-contained packages of resistance that can be added to a circuit and are commonly used to divide voltage levels.

Series and Parallel Circuits

Applying Ohm’s Law

Now, let’s apply Ohm’s law to the following circuit (for exercise purposes only, circuits are theoretical) and calculate the voltage and current supplied to each load. The schematic below shows a supply circuit for a child’s bedtime toy. R1 represents the resistance value of the speaker and R2 shows the resistance value of the LEDs. R1 is equal to 430 Ohms, R2 is equal to 284 Ohms and the supply is a battery with 5VDC and 5A. What is the voltage supplied to the LEDs and to the speaker? First, we need to find the current in the loop once the belly is pressed and switch 1 (S1) closes. The supply offers 5 amps of current but the circuit will only use what is demanded by the loads. Using Ohm’s law, we can reconfigure the formula to solve for current in the loop, or I (loop) = V (loop)/ R (loop).  Using the supplied values, we can calculate that I (loop current) = 5VDC/714Ω = 7mA.

Ohm’s Law Applied to a Series Circuit

Kirchoff’s voltage law (kvl).

This voltage drop principle leads to another important law in basic electrical engineering, Kirchoff’s Voltage Law (KVL). This law states that the algebraic sum of the voltages in a closed loop is always equal to zero. If we only knew the supply potential and the voltage drop of R1, we could use KVL to find the other voltage drop. With KVL you have to follow the current path and use the polarities of the components shown. If current path is unknown you have to assume one. We will use the positive to negative (clockwise) path. V(supply) + V(1) + V(2) = 0 or -5VDC + (+3VDC) + (+V(2)). Solving for V(2), V(2) = 2VDC, which we know to be correct. KVL really comes in handy when there are multiple supplies in a loop or multiple loops.

Ohm’s Law Applied to a Parallel Circuit

Kirchoff’s current law (kcl).

Power Equation

One last equation that is useful to remember is the power equation, P = IE. P is for power measured in Watts, I is for current and the E is for voltage. This equation can be combined with Ohm’s law to solve for values that are unknown. For example: In Ohms law we know that I = E/R so combined with the power equation (P = IE) we get P = E (E/R) or P = E^2/R. Also, from Ohm’s we know that E = IR, so combine this with P = IE and we get P = I^2R. Using the previous parallel example, we can find the power consumed by the circuit. We know the voltage rating of the battery is 5VDC and we calculated the total resistance in the parallel circuit (171Ω). Using these two values, the power consumed by the toy would be: P(total) = (5VDC)^2/171Ω = 146mW. [hozbreak]

I hope this information helps to refresh that which may have been forgotten. It is in no way intended to encompass every possible scenario, equation or topic that is electricity or electrical circuits. To help further understand the ins and outs of electricity and electrical principles, search the plethora of electrical engineering books available online. One of the big industries spawned from electrical principles is automation. Automation is electricity working for you to accomplish a task. Further information on automation and how to apply it can be found in our eBook: Automation 101: An Industry Guide to Control System Engineering .
