Simulation of LDR / photoresistor -VARIABLE resistor in a circuit

Simple Electric Circuit Simulation showing the work of a photo resistor – variable resistorWhat the Simulation Shows The simulation models a Light Dependent Resistor (LDR) in a series voltage divider circuit powered by a 9 V battery. The circuit has two components in series: the LDR and a fixed 10 kΩ resistor. The central interaction […]

Simulation of LDR – light dependent resistor and led in a circuit

Simple Electric Circuit Simulation showing the work of a LDR -Light dependent resistor What it shows: A 9V circuit with an LDR (light dependent resistor) and LED. In darkness the LDR resistance is 1 MΩ — almost no current flows and the LED stays off. Slide the light up and resistance plummets to 500 Ω,

Simulation of electric circuit – thermistor at work

Simple Electric Circuit Simulation showing the work of a thermistor in a circuit A thermistor (short for thermal resistor) is a type of resistor whose electrical resistance changes significantly with temperature. It is one of the most common and sensitive temperature sensors used in electronics. Basic Working Principle Thermistors are made from semiconductor materials (usually
