E means also energy, so let's choose V. Energy = voltage × charge. E = V × Q. Some like better to stick to E instead to V, so do it.

 Voltage V = I × R = P / I = √(P × R) in volts V          Current I = V / R = P / V = √(P / R) in amperes A Resistance R = V / I = P / I2 = V2/ P in ohms Ω      Power P = V × I = R × I2= V2/ R in watts W

Electric voltage V = I × R      (Ohm's law formula)
Electric voltage = amperage × resistance

Please enter two values, the third value will be calculated.

 Electric voltage V volts Amperage I amps Resistance R ohms V = I × R              I = V ⁄ R              R = V ⁄ I
Electric power P = I × V      (Watt's power law formula)
Electric power = amperage × voltage

Please enter two values, the third value will be calculated.

 Electric Power P watts Amperage I amps Voltage V volts P = I × V              I = P ⁄ V              V = P ⁄ I

If the unit of power P = I × V and of voltage V = I · R is needed
