Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A balanced star-connected load has a line voltage of 460 V. Calculate the phase voltage and if the phase current is 8 A, find the total power consumed.

💡 Hint: Use the phase to line voltage relationships and remember P = 3 Vph Iph.

Challenge 2 Hard

In a star connection, if the neutral wire is carrying a current of 5 A when phase currents are 2 A, 3 A, and 4 A, verify if the load is balanced.

💡 Hint: Evaluate the vector addition of currents.
