How can I determine the voltage of the resistor?
Ohm's law can be used to determine the resistor voltage for any part in the circuit. Simple calculations, also based on Ohm's law, also allow the resistor's voltage over the resistors in the series or to calculate in parallel. Resistors are common components in electrical circuits and are produced in a number of forms. Most of them are marked with a standard band scale that can be easily read to determine the resistance and hence the voltage for the known current that can be expected in the resistor. Voltage (v) = current (i) x resistance (r). When the resistors are combined in the series, one by one can be used to determine the voltage via any given resistor in the series. Alternatively, it is possible to add the resistance of all resistors in the series and the Ohm law used to calculate the resistor of the voltage across the series.
Parallel resistors will have different current levels as the electric current will prefer the path of less resistanceAnd another current will flow through weaker resistors. Conductivity - reciprocal resistance - each resistor in the parallel configuration can be together to determine the overall conductivity of the resistor field. 1/R (total) = 1/R (1) + 1/R (2) until all resistors and resistance voltage can be set by OHM law.resistors are made of different substances and are available in many different shapes and sizes. Axial resistors are shaped as cylinders with wires protruding from each end to facilitate their assembly on the board. For most of the 20th century it was the most common diversity of the resistor. Resistors of other shapes and sizeis are commonly used, especially for very small electronic devices where axial resistors could be impractical.
The resistance of the standard axial resistor is usually marked on the resistor using a series of color stripes. Four or five stripes indicate the nominal value of resistance resistor and production tolerance - how wide can resistor LIdentify from this nominal value. These belts are black, brown, red, orange, yellow, green, blue, purple, green and white, which corresponds to nine nine nine for the first two lanes or the first three in five -band resistors. The remaining strips indicate the power of ten multiplier and scattering.
When evaluating a striped resistor, the value of the resistance can be determined from these branded strips. Once the resistance value is determined, the current flow above this resistor may be measured. Finally, the resistor's voltage can be calculated using Ohm's law.
