Resistors are the most commonly used component in electronics, as their purpose is to create specified values of current and voltage in a circuit. Since there's so much to understand about them, being ...

If there’s one thing that will surely blind us, its reading resistor color bands. It doesn’t help that red looks exactly like orange, brown and black are indistinguishable, and different component ...

This is a handy resistor colour code “calculator” that doesn’t need power supply or to be installed on a PC. As you know most resistors use coloured bands in order to show their value. So basically ...

When using a spreadsheet to calculate circuit values, determining “standard” component values to be used in subsequent calculations can produce more accurate results. This approach will also result in ...

Thanks to reader Alan Metcalfe for bringing this to Gadget Master's attention. He describes it as "a simple Mr Spock circular (resistor) calculator, to cut-out and make". The Resistor Code Calculator ...

Many times, the need arises to interface single-supply analog-to-digital converters (ADCs) and comparators to real-world signals like 5 V. Of course, it's possible to condition the signal using ...

Calculate the total resistance of the circuit. Calculate the current flowing in the \({3}\Omega\) resistor. Calculate the voltage across the \({8}\Omega\) resistor. Calculate the current flowing in ...
