From this, we conclude that; Current equals Voltage divided by Resistance (I=V/R), Resistance equals Voltage divided by Current (R=V/I), and Voltage equals Current times Resistance (V=IR).To calculate voltage, V: put your finger over V, this leaves I R, so the equation is V = I × R.
To calculate current, I: put your finger over I, this leaves V over R, so the equation is I = V/R
