This calculator determines current by voltage and resistance using ohm law
|Capacitor in Direct Current Circuit|
These online calculators computes various parameters for charging and discharging the capacitor with the resistor
|Battery discharge time depending upon load|
This article contains online calculators that can work out the discharge times for a specified discharge current using battery capacity, the capacity rating (i.e. 20-hour rating, 100-hour rating etc) and Peukert's exponent.
|Electricity, Work, and Power|
This online calculator can help you solve the problems on work done by the current and electric power. It can calculate current, voltage, resistance, work, power and time depending on what variables are known and what are unknown
