    What is the optimum voltage for an X-ray tube and why is it important?

    Hi all, I hope this is the right place for this question. What effect does increasing voltage have in an X-ray generator? What's the optimum voltage for the most efficient production of X-rays and why? Thanks

    Engineering When Does Voltage Across Resistor Equal Voltage Across Inductor in RL Circuit?

    I have been for the past week, I've found equations to find the current in the circuit, and the time constants of the exponensial curve, but not what I'm looking for

    Engineering When Does Voltage Across Resistor Equal Voltage Across Inductor in RL Circuit?

    Homework Statement A step input of 100V is applied to a resistor of 50Ω in series with an inductor of 10H at time t=0. Calculate the time at which the voltage across the resistor equals the voltage across the inductor Homework Equations Im not sure which equation to use, i know τ=L/R...
