How does high voltage current do not pass through filament of cathode in an x-ray tube?
Why does high voltage current not pass through cathode filament in an x-ray tube?
Why does voltage drop? Physics? Why do we use high voltage to transmit electrical power? What physically does it mean that current is lagging voltage in an inductor? Why do people say that current kills you not voltage? Why is electrical energy transmitted at high voltage and low current? What are the cathode and the anode made of in cathode ray experiment and why? Why does current flow opposite the direction of the battery? Why in electric circuit, current move from positive to negative terminal? Why not otherwise? What is the current in a resistor if two different voltage sources are across it? Why does current flow opposite the direction of the field inside the battery? Are high voltage transmission wires insulated? Why does LVDT use high voltage? Why current is flowing through the conductor? Why current flow due to electrons? What physically does it mean (current lag voltage in an inductor) and why? Why are high voltage power lines not insulated? What differentiates a high voltage wire from a normal wire? Why does voltage of a battery drop? How does current flow in a battery? Why does current flow through a capacitor even though the circuit is not complete? What is voltage? What exactly is voltage? When neutral and ground wires get interchanged, there is flickering in the tube lights. Why? Does current flow through a capacitor? If phase voltage is increased, what will happen to line voltage? How can we seperate voltage and current? Why does only one tube of induction starts from unit positive test charge? What is the best analogy to explain current and voltage to a layman? What is line voltage and phase voltage? When three 5V@1A batteries are connected togather, what will be the total current and voltage?
