Current Calculator: Easily Determine Amperage from Voltage, Resistance, or Power

Discover how to easily calculate electrical current with our comprehensive Amp Calculator Guide infographic, featuring key formulas and step-by-step instructions.

Use the Amp Calculator by selecting a formula, entering voltage-resistance, power-voltage, or power-resistance values, and reading the auto-converted current result. For example, 120 V and 15 Ω returns 8 A. Standard U.S. outlets supply 120 V RMS (NEC 2023), so the tool’s range easily covers everyday and industrial tasks.

Education Loan Calculator: Plan Your Student Debt Repayment Easily

Demystify your education loan with our comprehensive calculator guide infographic, offering insights into loan types, repayment strategies, and financial planning.

Estimate student-loan payments in seconds: enter amount, interest, term, payment frequency and optional grace period, then read the monthly (or quarterly/annual) bill, total repayment and total interest. A $18,500 loan at 4.75 % over 8 years costs about $232 each month and $3,772 in interest—roughly 20 % of the principal (calculated with the standard amortization formula). Federal rates now range from 5.50 % to 8.05 % (U.S. Dept. of Education, 2023).

Heart Rate Calculator: Measure BPM, Find Target Zones & Maximize Workouts

Unlock the power of heart rate monitoring with our comprehensive guide to exercise intensity zones and their impact on your fitness journey.

Count beats, enter the seconds, add your age (and resting heart rate if you know it), pick an intensity level, and the tool returns your current BPM, maximum heart rate, target zone, and heart-rate reserve. Exercising at 60–80 % of your maximum heart rate improves cardiorespiratory fitness without undue strain (ACSM Guidelines, 2021).
