About

Voltage Divider

This engineering utility calculates unknown values in a voltage divider circuit. It can solve for voltages or resistor values, displaying ideal and actual resistor options. It also shows current, power, and voltage tolerance.

Highlights
  • Solves for Vin, Vout, R1, or R2
  • Resistor picker with actual values
  • Displays ideal resistor value
  • Calculates voltage tolerance
  • Shows current and power consumption
Features
Read full description

A handy engineering utility that solves for voltages or resistor values in a common voltage divider circuit. Enter three terms (out of Vin, Vout, R1 or R2) and this app will solve for the fourth term automatically. The resistor picker will only let you pick from actual resistor values that exist. It's a great time saving tool for quickly selecting resistor values in a switching power supply design or any other circuit that incorporates a voltage divider. When solving for a voltage, select two resistor values and one of the voltages. The remaining voltage will be displayed automatically. The max and min possible voltages will also be displayed based on the resistor tolerances. The current and power through the divider will be displayed at the bottom of the screen. When solving for a resistor value, select two voltages and one resistor value. The remaining resistor value will be displayed in yellow. This is an ideal value. Use the resistor picker to select an actual resistor value close to that ideal value. You can then tell the app to solve for Vin or Vout to see if the resulting voltage meets your design requirements.

About

CentraDesign Lite

This utility app calculates casing standoff and clearance for oil and gas wells. It considers various factors like pipe sizes, inclination, buoyancy, and side force. Users can visualize casing deflection in 2D and 3D.

Highlights
  • Bow spring and rigid centralizer database
  • Centralizer and casing database
  • Calculates casing standoff and clearance
  • Considers buoyancy and side force
  • 2D and 3D casing deflection view

CentraDesign Lite is condense version of CentraDesign, our centralizer placement software. CentraDesign Lite includes bow spring and rigid centralizer and provides centralizer and casing database. This app calculates one span of casing standoff and clearance, using any combination of hole, pipe sizes and inclination angle. It also takes buoyance and side fore effect into consideration. The output results include the standoff and clearance at centralizer and mid span. Users are also able to view the casing deflection in 2D and 3D view.

Verdict

The call

The clearest difference is price: CentraDesign Lite at Free against Voltage Divider's $1.99. CentraDesign Lite also leads on rating (5.0 vs 2.7) and update cadence (every 21 months vs every 48 months). Voltage Divider's advantage is ratings volume (3 vs 1). On ads, in-app purchases and device support there is nothing between them.
