Power across a resistor equation
Web8. Power is P = I V. You can only relate it to resistance if you decided to fix one and replace the other by Ohm's law. Ohm's law states that voltage across a resistor is linearly … Web23 Jul 2024 · V- VR + VL = 0. The voltage drop across inductor and resistor is given by. VR = I × R and VL= L (di/dt) So, the RL circuit formula is given by. V = I × R + VL= L (di/dt) With the above equation, it can be stated that VR is based on the current ‘i’, whereas VL is based on the rate of change in current.
