Finding the Value of a Resistor by Color Codes
To calculate the value of a resistor using the color coded stripes on the resistor, use the following procedure.Step One: Turn the resistor so that the gold or silver stripe is at the right end of the resistor.Step Two: Look at the color of the first two stripes on the left end. These correspond to …

Finding Voltage and Current Using Ohm's Law
There is a simple relationship between current, voltage and resistance. This relationship is called Ohms Law. The formula is the following.Difference in Voltage = Current * Resistanceor DV = I * RThis is Form 1 of Ohm's Law.To find current and resistance the following forms can be used. They are th …

Basic Electrical Components
ResistorsResistors are components that have a predetermined resistance. Resistance determines how much current will flow through a component. Resistors are used to control voltages and currents. A very high resistance allows very little current to flow. Air has very high resistance. Current almost n …
