Ohms Law and Voltage through Resistor. Simple Design 2


SERIES-RESISTOR

In a circuit diagram, we can see a number of Resistors connected in series or parallel between the positive and negative rails. These resistors are controlling the voltage and current to the particular sections of the circuit. When we design a circuit, we should have an idea about the voltage and current requirements for each section of the circuit. Then only we can select the proper values of resistors. If you know this, you can easily answer the questions in Project Viva regarding the selection of resistors.

Ohms Law and LED Resistor. Simple Design 1


LED-RESISTOROhms law is a must in circuit design to calculate, Current, Resistance and Voltage in the different sections of a circuit. Ohms law simply represents the relationship between voltage, current and resistance. Let us see how Ohms law is applied to select the current limiting resistor for LED.
