Voltage divider
Calculates the output voltage of an ideal resistor divider.
RC time constant
Calculates the time constant of a simple resistor-capacitor circuit.
DC current divider for two branches
Calculates currents in two parallel resistive branches of an ideal current divider.
Unknown branch current from KCL
Calculates signed unknown branch current from current balance; a negative result means the opposite direction to the assumption.
Unknown voltage from KVL
Calculates signed unknown voltage from a loop balance using the supplied source/drop convention.
DC source loaded voltage
Calculates DC source terminal voltage from source voltage, current, and internal resistance.
DC source internal power loss
Calculates power loss in a source internal resistance from current and resistance.
Wheatstone bridge
Calculates bridge output voltage and an unknown resistance at balance.
RC charging capacitor voltage
Calculates capacitor voltage during charging of an ideal RC circuit.
RC discharging capacitor voltage
Calculates capacitor voltage during discharge of an ideal RC circuit.
RC charging time to voltage
Calculates the time for a capacitor in an ideal RC circuit to reach a target voltage.
