The power input measurement to a synchronous motor is done using the two- wattmeter method. Each of the wattmeters reads 40 kW at a certain operating condition. If now, the pf is changed to 0.8 lagging, what would be the new wattmeter readings?

A diode is a two-terminal, electronic device made using semiconductors that is designed to prevent current from flowing in a particular direction. The symbol is a triangle pointing in the direction that (positive) current is allowed to flow and a wall preventing (positive) current from flowing in the opposite direction: 1: A diode has two modes, "on" and "off". When "on", current flows, and when "off", no current flows. We generally view diodes as either "ideal" or "modeled", as described below. "Ideal" view of a diode + The "ideal" diode is either a short circuit or an open circuit. Specifically, when the voltage across its terminals is negative, no current flows, and when current flows, there is zero voltage across its terminals, as pictured below: Diode "Modeled" view of a diode +51 Diode V Ideal Diode "Off" i=0| + U≤0 + I Therefore, with current i and voltage v defined as shown on the left above, for an "ideal" diode: • Current i cannot be negative. Voltage v cannot be positive. .…
