Circuit Jar Jun 2026

Derive the expression for the current flowing in an RL circuit when a step input voltage $V$ is applied. Sketch the growth and decay of current with respect to time.

When dealing with any circuit jar that actually stores a charge—like a capacitor or Leyden jar—safety is paramount. Even small jars can hold a surprising amount of energy. Always use a discharge tool before touching the terminals to avoid a painful (and potentially dangerous) shock.

Using Nodal analysis, find the voltage at the nodes and the current through the $5\Omega$ resistor for a given circuit containing two current sources ($I_1=5A, I_2=10A$) and three resistors. circuit jar

Historically, the most famous "jar" in electronics is the Leyden jar. Invented in the 18th century, this was the world’s first capacitor. It consists of a glass jar coated with metal foil on both the inside and outside. ⚡ Stores high-voltage electric charges. Acts as a bridge in early spark-gap circuits. Demonstrates the principles of capacitance and insulation.

Answer all questions.

Here’s a deep, reflective text for a “circuit jar” — a conceptual or artistic piece where electronic components are sealed in glass, representing memory, connection, or trapped energy.

You shake it gently. Nothing lights up. And yet — the arrangement is perfect. Every path leads somewhere, even if nowhere is here. Every joint was soldered with purpose. Every chip was once a pupil, learning patterns we taught it before we grew afraid. Derive the expression for the current flowing in

A coil having a resistance of $10\Omega$ and an inductance of $0.05H$ is connected in series with a capacitor of $100\mu F$ across a $200V$, $50Hz$ supply. a. Calculate the impedance. b. Calculate the current drawn. c. Determine the power factor of the circuit.
