U=RI where R-resistance in ohm and I - current in Apmpere (A)
U- voltage in volts (V)
P=UI P- power in watts (W)
P=RI^2 and other combinations
DC generator equations
Ua=E-RaIa-DUp
Ue=ReIe
E=K*fi*omega
M=K*fi*Ia
fi= magnetic flux
omega=rad/sec (angular speed of generator)
DUp-brush voltage

DC Voltage Equation?
E=IR
Where E=voltage, R=resistance,I=current
Also written: I=E/R or R=E/I
For power:P=IE
You are free to substitute each for your specific purposes: For example, if we substitute IR for E in the power equation, we get P=I*I*R or P=I^2R.
These are pretty much the most widely used DC equations.

Ohms law: V=I*R, voltage equals current multiplied by resistance of the circuit. Or if there are reactive elements, V = I * Z, where Z is the total impedance of the circuit.
