(b) A wattmeter is designed to give a full scale deflection with a current coil (i.) and voltage coil current (ip) of 1.5 A and 1.0 mA, respectively. The fixed coil resistance (R.) and moving coil resistance (Rm) are 0.7 N and 150 k 2, respectively. Determine the following: (i) The maximum power which can be measured by the wattmeter. (ii) The voltage of the moving coil circuit to enable the full scale deflection for a current of 2.0 A when power dissipates in a load. The phase angle is 55°. (c) Blondel's theorem is used to specify the number of wattmeters for power measurement in a system of electrical conductors. Discuss the three (3) arrangements of a wattmeter method.

A. In the morning, the student plugs in a computer (240 W) to study physics, a microwave (800 W) to make breakfast, and a hair dryer (1200 W) to dry the hair. What is the overall current in this student's room, in Ampere? B. A circuit in a student’s room has a 15 A circuit breaker. In the morning, the student plugs in a computer (240 W) to study physics, a microwave (800 W) to make breakfast, and a hair dryer (1200 W) to dry the hair. Will this be enough to trip the circuit breaker? not enough information no, because the overall current is more than 15 A no, because the overall current is less than 15 A yes, because the overall current is less than 15 A yes, because the overall current is more than 15 A
