Resistor A resistor is a passive two terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines , among other uses. Resistors | Ohm's Law | Electronics Textbook Resistor values in ohms are usually shown as an adjacent number, and if several resistors are present in a circuit, they will be labeled with a unique identifier number such as R 1, R 2, R 3, etc. As you can see, resistor symbols can be shown either horizontally or vertically: Real resistors look nothing like the zig zag symbol. What Is A Resistor And What Does It Do? Build Electronic ... The resistor is a passive device and doesn’t do anything actively to your circuit. It’s actually a pretty boring device. If you add some voltage to it, nothing really happens. Well, maybe it gets warm, but that’s it. BUT, by using resistors, you can design your circuit to have the currents and voltages that you want to have in your circuit. Resistors in Circuits Practice – The Physics Hypertextbook The voltage in a circuit rises in a battery and drops in a resistor (when we follow the flow of conventional current). The rise in the battery is given as 12 V and the drops in each resistor can be found through repeated use of Ohm's law… PARALLEL RESISTOR CALCULATOR 1728.org This calculator can solve other math problems. Calculating resistors in parallel is PRECISELY the same as the calculations required for INDUCTORS in PARALLEL or for CAPACITORS in SERIES.. This calculator can be used for work problems. For example, 'A' can paint a room in 5 hours and 'B' can paint a room in 6 hours. How to Reduce Voltage with Resistors Maybe your circuit is running off of 5V, yet you want only 3V to feed into a particular circuit element. How can you get the 5 volts into 3V? And you can do so with the correct resistor values in a voltage divider circuit. How do you calculate it? The formula for calculating the voltage that falls across the R2 resistor is shown below.
