All the Dynamometer Type Wattmeter Questions & Answers given below include a hint and a link wherever possible to the relevant topic. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up on the fundamentals of Dynamometer Type Wattmeter. Energy or power used in any system or environment is to be measured using Wattmeter. Typically, the active type of power is measured by these meters. Electric power estimation becomes easier with the installation of a wattmeter but the flowing of current excessively leads to device damage. The power consumed by the devices is monitored using Wattmeter. For the convenience of mankind, both digital and electric-type wattmeters are within reach. Based on the energy transferred and the amount of electricity flowing in a circuit (i.e., number of watts) Wattmeters are further classified as Electrodynamometer & Induction type Wattmeters. Energy transferred due to the flow of electric currents is measured by using an Electrodynamometer type wattmeter. This meter consists of wires in pairs in which the current is flowing among them. The magnetic field produced due to such current flow is measurable by placing a Voltmeter. Hence, the current measured in terms of voltage makes it easier in calculating the energy transferred. Electrodynamometers are mostly used in generators and electric motors. Primarily, this type of wattmeter contains fixed & moving coils. To obtain a higher range of accuracy it must be designed carefully. 1). AC & DC powers are measured using _________? Induction Wattmeter Electrodynamometer Ohmmeter Ammeter Hint 2).
