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 and Ohm’s law- resistor, voltmeter, ammeter

Simple Electric Circuit Simulation showing the work of a resistor, voltmeter, ammeter in a circuit What it shows: A simple series circuit — battery, resistor, ammeter, and voltmeter connected by copper cables. Electrons (green dots) flow around the loop. Crank up voltage or drop resistance and they speed up instantly. The resistor glows red as
