Question 21
INMCQ1 markNeeds review
In a single-phase AC circuit, the power consumed by load resistance
for an excitation
is measured using a wattmeter. The same wattmeter is connected in two different topologies, Topology-A and Topology-B, as shown in the figure. Different branch currents and voltage drops are also marked in the figure. Among the following options, the condition that ensures low error in the wattmeter reading for both the topologies is
