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, […]

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

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

Simple Electric Circuit Simulation showing the work of fuse in a circuit How to Use Suggested Activity Before adding loads, predict what will happen to the lamp, the current, and the fuse as more appliances are connected. Record the current at each stage and identify the exact point the fuse blows. Consider: why is the
