# CTE Resource Center - Verso - Electronics Systems I Task 1859759658

# Compute electrical power in circuits.

## Definition

Computation should include
• using the same value components that are physically installed in the circuit
• retaining at least three significant figures (i.e., decimal places) on all measurements
• reconciling differences between computed and measured values (often attributable to rounding errors).

## Process/Skill Questions

• Why might computed values differ from measured values?
