Calculates dc power / voltage / current / resistance.
Enter 2 values to get the other values and press the Calculate button:
The resistance R in ohms (Ω) is equal to the voltage V in volts (V) divided by the current I in amps (A):
The resistance R in ohms (Ω) is equal to the squared voltage V in volts (V) divided by the power P in watts (W):
The resistance R in ohms (Ω) is equal to the power P in watts (W) divided by the squared current I in amps (A):
The current I in amps (A) is equal to the voltage V in volts (V) divided by the resistance R in ohms (Ω):
The current I in amps (A) is equal to the power P in watts (W) divided by the voltage V in volts (V):
The current I in amps (A) is equal to the square root of the power P in watts (W) divided by the resistance R in ohms (Ω):
The voltage V in volts (V) is equal to the current I in amps (A) times the resistance R in ohms (Ω):
The voltage V in volts (V) is equal to the power P in watts (W) divided by the current I in amps (A):
The voltage V in volts (V) is equal to the square root of the power P in watts (W) times the resistance R in ohms (Ω):
The power P in watts (W) is equal to the voltage V in volts (V) times the current I in amps (A):
The power P in watts (W) is equal to the squared voltage V in volts (V) divided by the resistance R in ohms (Ω):
