THE RELATIONSHIP BETWEEN CAPACITORS AND RESISTORS - USING CIRCUIT WIZARD ELECTRONICS SIMULATION SOFTWARE |
||

Electronics software such as Circuit Wizard is perfect for testing circuits without actually building them from real components. |
||
Both capacitors and resistors are important components in circuits,
especially delay or timer circuits. Combining resistors and capacitors
in a circuit will increase / decrease a timing sequence. |
||
The total capacitance is calculated by simply adding the values of the capacitors together. |
||
Using electronics software such as Circuit Wizard, change the resistor values to 1K. When the switch is closed the LED lights almost immediately. When the switch is opened the LED stays alight for a longer time and fades more slowly until final it emits no more light. Increasing the value of the resistor causes the capacitors to charge up more slowly. Most important of all, when the switch is opened the capacitors discharge their electricity more slowly. The LED stays alight for a longer time | ||
QUESTIONS: 1. Using simulation software such as Circuit Wizard, build a capacitor and resistor circuit incorporating a relay. The relay should remain energised for a short time after the circuit switch is opened. |
