Examples 📘⚡

Example 1: Resistor Calculation

An LED circuit requires:

• Supply Voltage = 12V
• LED Voltage = 2V
• Current = 20mA

Required resistor:

R = (12 − 2) / 0.02

R = 500 Ω

P = 24 × 3

P = 72W

Example 3: Capacitor Reactance

Given:

• Frequency = 1000 Hz
• Capacitance = 1 µF

Reactance:

Xc = 1/(2πfC)

Xc ≈ 159 Ω

This information helps engineers design filters and AC circuits.
