Resistance calculator

Introduction

• Calculate the resistance of a network of resistors.
• The resistors can be connected in series or parallel.
• Use infix or RPN to state the network.
• Calculate resistance, voltage, current and power for every resistor and operation.

Background

• Serial Resistors: the sum of the resistors gives the equivalent resistor
• Parallel Resistors: the inverse of the sum of the inverse of the resistors
• The voltage drops over the resistors
• Current = Resistance / Voltage
• Power = Current * Voltage

• Infix: ((((R8 + R10) * R9 + R7) * R6 + R5) * R4 + R3) * R2 + R1
• RPN: 10 2 + 6 * 8 + 6 * 4 + 8 * 4 + 8 * 6 +

Output for voltage 18.0 V

• 10.000 ohms in the upper left corner is the equivalent resistance.
• The first operation is 10 + 2 = 12 which can be found in the three middle rows.
